XF 1.5 How to make "Search this thread only" default check on thread view?

[rdn]

And also set "Search this forum only" default check on forum view?

I tried adding checked="checked" on search_bar_thread_only template

and remove the same code on search_bar_forum_only.

It works fine on thread view, but on forum view "Search this forum only" is not check by default.

Tried with Conditional, but didn't work:
