Thanks for all your effort! I haven't tinkered with mealmaster files in ages but you've given me a reason to dig through my old CDs to find my archives. Unlike zip files of old code or software, recipes are likely just as useful today as they were 10 or 20 years ago.
One thing I noticed when working with Sqlite3 recently is that they've implemented full text searching.

I found the implementation simple to employ and incredibly fast and powerful. Perhaps it could be a helpful tool in a generic search? Just an idea!
