'How to use received user data for automatic search/selection of desired content?

I'm developing my own web site in order to make movie choosing as convenient as possible. I've already made up a landing page that contains a header where you can find a button which transfers you to a questionnaire form which aim is to collect needed data from user to find and show a list of desired films on the other page. My problem: I have no clue how to use collected data from a user to find desired movies. I guess that I just ought to connect a huge library of films to find appropriate ones, using key words, typed or chosen by a user. However, I don't know what to do as I haven't had such experience yet.

I'm attaching a link to my web site if you would like to investigate: https://rohanian73.github.io/

I would be more than grateful for any explanations or suggestions. Thank you very much for taking the time to read this post. All the best!

After getting data from the user, you can use any free api to get desired data. API is something that can get data from a remote database.
Here's a free api link, it's called OMDb API. To use this api you must have a api key which available when you click the header API Key option.
You can use parameters to query data using this api. Read their documentation for details.
