Set the default search to title only

[Firnus]

Hi,
I like to set the default search to title only.

1. Search in title by default with quick search
2. Check automatically the title only in adcandec search

For 2 : i can do it via theme
But for 1 i didn't find how to do this ?

I see the event search_do_search_start , but no way to set default search since it get by

"postthread" => $mybb->get_input('postthread', MyBB::INPUT_INT),

Any idea ?

Sorry …

header_quicksearch :

<input type="hidden" name="postthread" value="2" />
