Some ideas come to mind...

Using the gravity forms quiz function or even simple multi choice / checkbox answers you create a form

Then create a simple view and you could setup another form that auto delete submissions and use it for your searching feature.
- this form would redirect with Entry ID and then load the gravity view you had created previously. If it was successful it would show the entry or if it wasn’t it would ya not found and try again.

If the view is too much of a hassle GravtiyWiz has a feature that allows for populating entry onto a page content using the Private EID as they refer to it. This would give another way of not revealing a entry ID some security concerns in knowing the exact record ID. To populate a WP Page with the merge tags.

I’ve done this in the past for a large student portal.

Make sure you have logical URL structures and thoroughly test the urls with either EID (gravity wiz) or using entry IDs with gravity view.

Best of luck!
