Webflow Collection search

Hello friends

I am having difficulty a search system for my client’s CMS database of over 5000.

This is the flow of the website:
On the home page, users input their address, this generates their zip code
The zip code generated is then to be used to filter through the CMS database such that on the pricing page, it shows the CMS item that has the zip code generated.

I have been able to create the system that generates the zip code from the address input but I have not been able to create the search system such that only pricing options available for the zip code is displayed on the pricing page.

Lots of solutions I have seen to filter through webflow collection only work for the first 100 collection list.

Can anyone here help with it?
