First of all, thank for looking at thread. I want to modify the default search functionality. This includes:
1. Changing the query to search beyond the posts and pages. I have other tables set up that I want to be included in the search.
2. Change the display of the search results.
Please let me know which file(s) I should be looking at. I would appreciate if someone can point to me or explain to me how the default search works, ie where is the search keyword being passed to, which functions is called to perform the search.
