Fix the search parameters of a Web App and then display the results?

[Burland Creative]

Is it possible to predefine the search results of the Web App and then have the results displayed when the user arrives on the search page?

I'm trying to display a list of items that appear in multiple categories only. For example:

When you use the search option you can request that the results only show you items that appear in categories A, C and D. To be clear, I don't need to see a list of all the items in categories A, C and D, only the items that appear in all three categories.

Any ideas? There doesn't seem to be anyway of doing this via the Toolbox, sadly.

One way I know of is using ajax to perform the search when the user lands on a page. This page will have the search form with only the fields that you wish to use to search on it. Hard code the "values". I will point out though, that since you are using javascript to fetch the results and then display them, it is not beneficial to seo, its as if nothing is showing.

I also wanted to add that this is also possible with liquid, but you are limited to a collection of 500 items. If you had a total of lets say 700 items, then it will not work. Yet.
