search inside posts and titles ?
 

When searching for something on a vbulletin forum, you have to select wether you want to search for a word inside the topic titles or inside the post content.
Is there a way to look for the query inside both ? So it would search inside posts content and topic titles at the same time ?

I'm not sure as I haven't tried it myself, but if you look at the code of search inside topic and inside words, you will get the idea how to implement the combination of both at the same time.

I guess you are right about your idea, though

As fxdigi-cash stated, look at the code for the searchbit. There will 2 be options inside there, copy one and add the second in the same tags. This SHOULD in theory create another option. Be sure to rename the option to "Both", or it will show a duplicate of the one you've copied first.
