Thanks, that worked, but i'm not sure if it's 100%. I have files I know to contain an search term that are not being picked up. Is the search case sensitive? Are there any known quirks with the text content search?
I am looking in folders that are indexed and other queries do seem to match the contents. The files are TaskPaper and FoldingText files so they have a .tp and .ft extension and different file type but they are still just plain text inside.
