Answer 1

Here is the Answer to your Question:
I don't see any such errors/issues in your code. A few words about the solution:
Chrome browser sometimes doesn't opens maximized so you need to maximize the Chrome browser using ChromeOptions class.
If the browser is not maximized certain elements doesn't appers within the Viewport and and may throw NoSuchElementException
Add the argument to disable the infobars through ChromeOptions class.
Your xpath looks vulnerable to me, try to construct logical xpath for the elements on the HTML DOM.
Your own code works at my end with some simple tweaks which opens the Chrome
Browser, navigates to the URL https://www.flipkart.com/, searches for Bag, clicks on Skybags Pixel Plus 03 30 L Backpack and Skybags Pixel Plus 03 30 L Backpack (Grey) is opened in a new tab.
Here is the modified code block:
System.setProperty("webdriver.chrome.driver","C:\\your_directory\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized");
options.addArguments("disable-infobars");
WebDriver driver = new ChromeDriver(options);
driver.get("https://www.flipkart.com/");
driver.findElement(By.name("q")).sendKeys("Bag");
driver.findElement(By.xpath("html/body/div[1]/div/header/div[1]/div[2]/div/div/div[2]/form/div/div[2]/button")).click();
driver.findElement(By.xpath(".//*[#id='container']/div/div[2]/div[2]/div/div[2]/div/div[3]/div[1]/div[1]/div[1]/div/a[2]")).click();
Let me know if this Answers your Question.

Answer 2

I have tried the same lines of code which you have mentioned and things work for me. Maybe you should try again.
Please try to use small xpath:
Suggestion:
Replace Xpath: html/body/div[1]/div/header/div[1]/div[2]/div/div/div[2]/form/div/div[2]/button with the different Xpath:
//form[#action="/search"]/div/div[2]/button
You should use relative path instead of absolute path because if there are any changes made in the path of the element then that XPath gets failed.

Answer 3

I got the same exception and added implicitly wait. It is working fine now. The code
System.setProperty("webdriver.chrome.driver",System.getProperty("user.dir") + "\\lib\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.get("https://www.flipkart.com/");
driver.findElement(By.name("q")).sendKeys("Bag");
driver.findElement(By.xpath("html/body/div[1]/div/header/div[1]/div[2]/div/div/div[2]/form/div/div[2]/button")).click();
driver.findElement(By.xpath("//*[#class='_2cLu-l']")).click();`

Answer 4

Final solution and I can't suggest more than this,
//openChromeBrowser();
driver.get("https://www.flipkart.com/");
driver.findElement(By.name("q")).sendKeys("Bag");
driver.findElement(By.xpath("//form[#action='/search']/div/div[2]/button")).click();
Thread.sleep(5000);
driver.findElement(By.linkText("Puma PUMA Zipper Backpack 26 L Laptop Backpack")).click();
1> Give some wait time and it works
2> Use LinkText for locators for any of the item shown.
