Do you have a suggestion of where and what file type is best to upload the message transcription so that it is searchable? Or does the searching rely on what we use as tags when the file is uploaded?
One amazing feature of Message Catalogue is the ability to search for keywords from previous sermons and series by tag or transcripts. For transcripts, any text-readable document will work. So, PDF, Doc, Docx, Txt, etc. However, Apple Pages documents are not text-extracted at this time.
If you upload any document that is text-readable, then that content will be available to search. Keyword tags do take priority in the search, but transcripts are great for phrases and such. You can even add a single quote " at the end of the search to get exact if you want.
