"Let's start by initializing a simple vector store retriever and storing the 2023 State of the Union speech (in chunks). We can set up the retriever to retrieve a high number (20) of docs."
"And with an unwavering resolve that freedom will always triumph over tyranny. \n",

"Six days ago, Russia’s Vladimir Putin sought to shake the foundations of the free world thinking he could make it bend to his menacing ways. But he badly miscalculated. \n",
"\n",
"He thought he could roll into Ukraine and the world would roll over. Instead he met a wall of strength he never imagined. \n",
"And tonight I am announcing that we will join our allies in closing off American air space to all Russian flights – further isolating Russia – and adding an additional squeeze –on their economy. The Ruble has lost 30% of its value. \n",
"\n",
"The Russian stock market has lost 40% of its value and trading remains suspended. Russia’s economy is reeling and Putin alone is to blame.\n",
"I spent countless hours unifying our European allies. We shared with the world in advance what we knew Putin was planning and precisely how he would try to falsely justify his aggression. \n",
"\n",
"We countered Russia’s lies with truth. \n",
"\n",
"And now that he has acted the free world is holding him accountable.\n",
"And now that he has acted the free world is holding him accountable. \n",
"\n",
"Along with twenty-seven members of the European Union including France, Germany, Italy, as well as countries like the United Kingdom, Canada, Japan, Korea, Australia, New Zealand, and many others, even Switzerland. \n",
"\n",
"We are inflicting pain on Russia and supporting the people of Ukraine. Putin is now isolated from the world more than ever. \n",
"\n",
"Together with our allies –we are right now enforcing powerful economic sanctions.\n",
"To all Americans, I will be honest with you, as I’ve always promised. A Russian dictator, invading a foreign country, has costs around the world. \n",
"\n",
"And I’m taking robust action to make sure the pain of our sanctions is targeted at Russia’s economy. And I will use every tool at our disposal to protect American businesses and consumers. \n",
"\n",
"Tonight, I can announce that the United States has worked with 30 other countries to release 60 Million barrels of oil from reserves around the world.\n",
"And we remain clear-eyed. The Ukrainians are fighting back with pure courage. But the next few days weeks, months, will be hard on them. \n",
"\n",
"Putin has unleashed violence and chaos. But while he may make gains on the battlefield – he will pay a continuing high price over the long run. \n",
"\n",
"And a proud Ukrainian people, who have known 30 years of independence, have repeatedly shown that they will not tolerate anyone who tries to take their country backwards.\n",
"Tonight I say to the Russian oligarchs and corrupt leaders who have bilked billions of dollars off this violent regime no more. \n",
"\n",
"The U.S. Department of Justice is assembling a dedicated task force to go after the crimes of Russian oligarchs. \n",
"\n",
"We are joining with our European allies to find and seize your yachts your luxury apartments your private jets. We are coming for your ill-begotten gains.\n",
"America will lead that effort, releasing 30 Million barrels from our own Strategic Petroleum Reserve. And we stand ready to do more if necessary, unified with our allies. \n",
"\n",
"These steps will help blunt gas prices here at home. And I know the news about what’s happening can seem alarming. \n",
"\n",
"But I want you to know that we are going to be okay. \n",
"\n",
"When the history of this era is written Putin’s war on Ukraine will have left Russia weaker and the rest of the world stronger.\n",
"Our forces are not going to Europe to fight in Ukraine, but to defend our NATO Allies – in the event that Putin decides to keep moving west. \n",
"\n",
"For that purpose we’ve mobilized American ground forces, air squadrons, and ship deployments to protect NATO countries including Poland, Romania, Latvia, Lithuania, and Estonia. \n",
"\n",
"As I have made crystal clear the United States and our Allies will defend every inch of territory of NATO countries with the full force of our collective power.\n",
"While it shouldn’t have taken something so terrible for people around the world to see what’s at stake now everyone sees it clearly. \n",
"\n",
"We see the unity among leaders of nations and a more unified Europe a more unified West. And we see unity among the people who are gathering in cities in large crowds around the world even in Russia to demonstrate their support for Ukraine.\n",
"From President Zelenskyy to every Ukrainian, their fearlessness, their courage, their determination, inspires the world. \n",
"\n",
"Groups of citizens blocking tanks with their bodies. Everyone from students to retirees teachers turned soldiers defending their homeland. \n",
"\n",
"In this struggle as President Zelenskyy said in his speech to the European Parliament “Light will win over darkness.” The Ukrainian Ambassador to the United States is here tonight.\n",
"In the battle between democracy and autocracy, democracies are rising to the moment, and the world is clearly choosing the side of peace and security. \n",
"\n",
"This is a real test. It’s going to take time. So let us continue to draw inspiration from the iron will of the Ukrainian people. \n",
"\n",
"To our fellow Ukrainian Americans who forge a deep bond that connects our two nations we stand with you. \n",
"\n",
"Putin may circle Kyiv with tanks, but he will never gain the hearts and souls of the Ukrainian people.\n",
"Together with our allies we are providing support to the Ukrainians in their fight for freedom. Military assistance. Economic assistance. Humanitarian assistance. \n",
"\n",
"We are giving more than $1 Billion in direct assistance to Ukraine. \n",
"\n",
"And we will continue to aid the Ukrainian people as they defend their country and to help ease their suffering. \n",
"\n",
"Let me be clear, our forces are not engaged and will not engage in conflict with Russian forces in Ukraine.\n",
"My administration is providing assistance with job training and housing, and now helping lower-income veterans get VA care debt-free. \n",
"\n",
"Our troops in Iraq and Afghanistan faced many dangers. \n",
"\n",
"One was stationed at bases and breathing in toxic smoke from “burn pits” that incinerated wastes of war—medical and hazard material, jet fuel, and more. \n",
"\n",
"When they came home, many of the world’s fittest and best trained warriors were never the same. \n",
"And tonight I am announcing that we will join our allies in closing off American air space to all Russian flights – further isolating Russia – and adding an additional squeeze –on their economy. The Ruble has lost 30% of its value. \n",

"\n",
"Together with our allies –we are right now enforcing powerful economic sanctions.\n"
" 'result': 'Russia has been subjected to powerful economic sanctions, including cutting off its largest banks from the international financial system, preventing its central bank from defending the Russian Ruble, and choking off its access to technology. Additionally, American airspace has been closed to all Russian flights, further isolating Russia and adding pressure on its economy. These actions have led to a significant devaluation of the Ruble, a sharp decline in the Russian stock market, and overall economic turmoil in Russia.'}"
"One of the most serious constitutional responsibilities a President has is nominating someone to serve on the United States Supreme Court. \n",
"\n",
"And I did that 4 days ago, when I nominated Circuit Court of Appeals Judge Ketanji Brown Jackson. One of our nation’s top legal minds, who will continue Justice Breyer’s legacy of excellence.\n",
"As I said last year, especially to our younger transgender Americans, I will always have your back as your President, so you can be yourself and reach your God-given potential. \n",
"\n",
"While it often appears that we never agree, that isn’t true. I signed 80 bipartisan bills into law last year. From preventing government shutdowns to protecting Asian-Americans from still-too-common hate crimes to reforming military justice.\n",
"A former top litigator in private practice. A former federal public defender. And from a family of public school educators and police officers. A consensus builder. Since she’s been nominated, she’s received a broad range of support—from the Fraternal Order of Police to former judges appointed by Democrats and Republicans. \n",
"\n",
"And if we are to advance liberty and justice, we need to secure the Border and fix the immigration system.\n",
"From President Zelenskyy to every Ukrainian, their fearlessness, their courage, their determination, inspires the world. \n",

"Groups of citizens blocking tanks with their bodies. Everyone from students to retirees teachers turned soldiers defending their homeland. \n",

"In this struggle as President Zelenskyy said in his speech to the European Parliament “Light will win over darkness.” The Ukrainian Ambassador to the United States is here tonight.\n",
"But that trickle-down theory led to weaker economic growth, lower wages, bigger deficits, and the widest gap between those at the top and everyone else in nearly a century. \n",
"\n",
"Vice President Harris and I ran for office with a new economic vision for America. \n",
"\n",
"Invest in America. Educate Americans. Grow the workforce. Build the economy from the bottom up \n",
"I spoke with their families and told them that we are forever in debt for their sacrifice, and we will carry on their mission to restore the trust and safety every community deserves. \n",
"\n",
"I’ve worked on these issues a long time. \n",
"\n",
"I know what works: Investing in crime prevention and community police officers who’ll walk the beat, who’ll know the neighborhood, and who can restore trust and safety. \n",
"\n",
"So let’s not abandon our streets. Or choose between safety and equal justice.\n",
"Madam Speaker, Madam Vice President, our First Lady and Second Gentleman. Members of Congress and the Cabinet. Justices of the Supreme Court. My fellow Americans. \n",
"\n",
"Last year COVID-19 kept us apart. This year we are finally together again. \n",
"\n",
"Tonight, we meet as Democrats Republicans and Independents. But most importantly as Americans. \n",
"\n",
"With a duty to one another to the American people to the Constitution. \n",
"\n",
"And with an unwavering resolve that freedom will always triumph over tyranny.\n",

"\n",
"And fourth, let’s end cancer as we know it. \n",
"\n",
"This is personal to me and Jill, to Kamala, and to so many of you. \n",
"\n",
"Cancer is the #2 cause of death in America–second only to heart disease.\n",
"When we invest in our workers, when we build the economy from the bottom up and the middle out together, we can do something we haven’t done in a long time: build a better America. \n",
"\n",
"For more than two years, COVID-19 has impacted every decision in our lives and the life of the nation. \n",
"\n",
"And I know you’re tired, frustrated, and exhausted. \n",
"My plan to fight inflation will lower your costs and lower the deficit. \n",
"\n",
"17 Nobel laureates in economics say my plan will ease long-term inflationary pressures. Top business leaders and most Americans support my plan. And here’s the plan: \n",
"\n",
"First – cut the cost of prescription drugs. Just look at insulin. One in ten Americans has diabetes. In Virginia, I met a 13-year-old boy named Joshua Davis.\n",
"And soon, we’ll strengthen the Violence Against Women Act that I first wrote three decades ago. It is important for us to show the nation that we can come together and do big things. \n",
"\n",
"So tonight I’m offering a Unity Agenda for the Nation. Four big things we can do together. \n",
"\n",
"First, beat the opioid epidemic. \n",
"\n",
"There is so much we can do. Increase funding for prevention, treatment, harm reduction, and recovery.\n",
"My plan will not only lower costs to give families a fair shot, it will lower the deficit. \n",
"\n",
"The previous Administration not only ballooned the deficit with tax cuts for the very wealthy and corporations, it undermined the watchdogs whose job was to keep pandemic relief funds from being wasted. \n",
"\n",
"But in my administration, the watchdogs have been welcomed back. \n",
"\n",
"We’re going after the criminals who stole billions in relief money meant for small businesses and millions of Americans.\n",
"I remember when my Dad had to leave our home in Scranton, Pennsylvania to find work. I grew up in a family where if the price of food went up, you felt it. \n",
"\n",
"That’s why one of the first things I did as President was fight to pass the American Rescue Plan. \n",
"\n",
"Because people were hurting. We needed to act, and we did. \n",
"\n",
"Few pieces of legislation have done more in a critical moment in our history to lift us out of crisis.\n",
"One of the most serious constitutional responsibilities a President has is nominating someone to serve on the United States Supreme Court. \n",
"\n",
"And I did that 4 days ago, when I nominated Circuit Court of Appeals Judge Ketanji Brown Jackson. One of our nation’s top legal minds, who will continue Justice Breyer’s legacy of excellence.\n",
