Advanced Search with Multiple Search Bars

I am looking for adding an advanced search filter on a website where users can type in part dimensions and tolerance into individual search bars to populate products that meet their parameters. 

To understand what I mean, I am attaching a screenshot from their current website, which shows an example of how their customers currently search.

I have looked into this option: https://www.squarewebsites.org/squarespace-plugins/universal-filter

But I'm looking for search bars vs. dropdowns as there will be hundreds of options to filter.
