How to make a search engine in a website? HTML

Question

Can someone tell me, or give me a piece of code, which has a search engine that searches up words from the website! Thank you!

Answer 1

You can't in plain html, but you can in JavaScript, you have to get all text in a page and use for example:
myText.indexOf("word you're looking for");
in JavaScript, to see if there's the data you're looking for, indexOf will return the index of the first character that matches your search value
