My IDE of choice is Komodo. With the recent changes in WordPress from development scripts (.dev.*) to minified scripts (.min.) I had to make some tweaks to my WP projects so my searches aren’t constantly returning strings from the minified versions of these files. You can ignore these files in your current project by going to Project->Properties, choosing “Project Preferences” on the left, and adding
*.min.* to the semi-colon separated list (so make sure to add a semi-colon where needed) of “Files and directories to exclude”.
