I’ve found that searching for songs with apostrophe’s in the title (It’s, We’re etc) requires “breaking” the apostrophe for a successful search – doing a double apostrophe (It”s, We”re etc) seems to be a workaround for the issue but people who don’t know this trick won’t have a good experience
Additionally, fat-fingering searches for bibles and inserting invalid characters (double colons, apostrophes etc) seems to make the whole program freeze for a couple of minutes and you can’t do anything at all – I’m not sure if there is an easy solution for this – maybe defining valid characters for the search and ignoring everything else or stopping the search when anything other than a-z, 0-9, hyphen and colon is detected?
