My site uses custom fields extensively, but the search doesnt look in the custom fields. Is there a plugin that works for 1.5.2 that will allow this to happen?
An example would be if one had a custom field for current mood, and a user wanted to search for all the posts when you were 'sad.' Currently, you can't do it.
You can try on my site now. the stuff in the righthand columns of the tables is all non-searchable custom feilds.
