Custom Page - able to be found through Search?
 

Is it possible to include the data on custom pages within vBulletin search results?

I'm not sure how the search function works exactly (...I'm a designer, not a coder), so this may be a silly question, for various reasons. For all I know it could be easy... or obscenely difficult, or impossible. Can anyone shed some light on this for me, please?

I'm sure there is at least one hook for the search query where you could add your particular search keywords to the regular query via plugin.

Just look through the search.php for available hooks.

You may want to ask in the paid section if you want someone else to code that for you.
