In Mac OS X 10.5 Leopard through at least Mac OS X 10.11 El Captain, when you typed in the search box in Finder, a silver bar would appear below it. Starting from the left side of this bar, there is the text
Search: and next to it there are two buttons that say
This Mac and the name of the current folder in double quotes. In Mac OS X 10.5 Leopard, and possible Mac OS X 10.6 Snow Leopard, there were two more buttons all the way over to the right that said
Names (or maybe it was
Contents was selected, then Finder would look inside files for the text that is typed into the search bar.
I'm on Mac OS X 10.11 El Capitan right now and there is no such choice of buttons (i.e., between
Contents). This has bugged me for several years, but now I'm done ignoring it. How can I make Finder search in files' contents? I presume that on the older version of Mac OS X, when Finder searched file contents, it didn't change the
Last opened date of each file, too (which is how I want it). I don't want to use
grep or another application. I want to make Finder behave like this. I will only accept an alternative browser application if it is sufficiently like Finder in terms of features and design.
