I have been using Komodo Edit for a couple years now and love it, especially the Find In Files feature.
I am very familar with how to use, and was using it yesterday when all of a sudden it decided to tell me that “No Files Were Found To Search In”
Search In was set to File and I double and triple checked the filename I typed in Include was correct and then removed and re-added the Directories section, but still told me the same thing.
I was very confused for quite a while until I realized that I had accidentally UNchecked the Search In Sub-Directories box.
Glad you resolved your issue and thanks for sharing your experience. You can also use the open/find toolbar (instead of the Find Dialog) as a way to search within files: http://docs.activestate.com/komodo/8.5/search.html#search_find_toolbar
with keyboard shortcuts (Alt+i, or Ctrl+i on Mac) to focus into the textbox field. You can also use relative paths like “.” and “…” to search relative from the current editor file.
