Well I had checked the Database for "Deportee", and when I was told "Sorry, no documents were found which match your query", I didn't even bother to check for "Deportees", because I assumed that "Deportee" would have been recognised as a _part_ of the longer word "Deportees", if either word were in the Database.
Did indeed find the song when I rechecked for "Deportees".
I gather that the search for text within the Forum Threads _is_ this kind of "inclusive" search (sorry, I don't know the technical name) where, for example, a search for "Art" will retrieve both "Arthur" and "Martin". Perhaps it would be a good idea to include this in the Database Search as well - either as the default mode, or at least as an option (if it is felt to be too inclusive for general use).
Thoughts on this?
