How to change Default setting to FULL-TEXT SEARCH Plugin to ->CONTENT Based Search instead Of "Revision Search"

For non-admin user "Content based" and "Revision search" both content are not visible.

Thank you.

The Doku I have refer before writing the post and now again after your recommendation. It contain everything about when where and how to use FULL_TEXt search.

I do know that for each user similar to Project Option query, the scheme will saved in system project under user id project. But how to make Default "Content based" instead of "Attributed search"

The profile saved does change and make default search mode as "Content based" As always whenever we open FULL_TEXT search it open initially "Attribute search" mode.
