I have just scanned and imported a couple of hundred photos. After import I have renamed most. I have ben trying to find specific pics using the search function. I assumed that it would search by title, but it doesn't seem to be working. For instance I know that there are 3 photos amongst 12,339 that are called 'portrait'. If I put his into the search (search by 'all' because it doesn't offer title) I get about 500 pictures selected and only one of the portrait's!........ what's going on?

Any suggestions gratefully received.
