Code for a boolean operator search function for only one specific page/database

I’m having trouble with
creating a code for a specific page that allows the user to use a Boolean operator search function to search that page’s database and that database only

Working in
WIX Editor

Site link
The site I am working on is not currently set up, but here is the link to what he currently has on WordPress that I am trying to replicate on WIX.

What I’m trying to do
I am hoping to create a search database for my client’s website, where a user is able to use Boolean operators to search through his database of articles

What I’ve tried so far
I don’t know much at all about code and need help setting this up or something I can copy and paste!

Extra context
I’m a mom of two under two and pretty brain fried/basically only speak toddler. Please help break this down for me as if I was one!

This will definately require code. I dont think there would be a copy paste code to easily drop in.

you would need to set up the search input value and trim.

const rawQuery = $w('#searchInput').value.trim();

and then run a function

function buildBooleanFilter(rawQuery) {
    const field = 'title'; 

    let query = rawQuery
        .replace(/\s+(AND|OR|NOT)\s+/gi, (match) => ` ${match.trim().toUpperCase()} `)
        .replace(/\s+/g, ' ')
        .trim();

would need more specifics to customize to suit requirements
