Find and replace in files not working with Brackets and Netbean

I want to get total control of my site for both source and content.

I tried to do a find in files in Bracket and Netbeans.

But it can’t find content text…

I tried with my Drupal localhost and everything can be found.

How can I search my wordpress localhost?

I have a multisite and want to be able to do batch changes to multiple styles sheets ect…
