Thanks for a prompt response.

I have a site with multiple pages, but these are the 3 main pages where I need to implement the search box.

Home page: The search box on this index page will show results from both Skill Tests Wix-data-collection and Virtual internships data-collection.

Skill Tests page: The search box on this page will show suggestions (in a dropdown) or search-results only from the Skill Tests Wix-data-collection.

Virtual Internships: The search box on this page will show suggestions (in a dropdown) or search-results only from both Virtual Internships Wix-data-collection.

Q.1 So is it possible for your tool to show the suggestions in a dropdown (after the keyword is entered in the searchbox) exclusively from specific data-collections?

Q.2 If the answer to the above question is Yes, then I'd like to know how many search results pages will your tool create?

a) It will only have ONE search results page to dynamically show the results from specific wix data collections.
b) It will have 3 search results pages, depending on where the search is being made.

Thanks,
Mottled

Yes, you can use SearchIQ to display the results from specific post types. You need to create separate search engine for different data collections and index the pages accordingly.
SearchIQ will have only one search page and not three search pages for different data collections. Please let us know if you need any help with the setup.
