I caption my football photos with each player's two digit jersey number, ie. 01-99. I then upload them to SmugMug with the intent of allowing viewers to use the "search" function to view photos of only their player. Unfortunately, the SmugMug search engine ignores any caption that has 2 or less characters. I would like to append all my football captions in Lightroom 3 with an additional identifier to lengthen the caption so it will become searchable, for example append the "01" to "Titans01". I don't care if identifier is at beginning or end. I just want to be able to append an entire album at one time, not just one at a time.
IIRC, John Beardsworth has a nice plug-in that will append a text string to existing captions. You can download & test it, then buy if it will work for you.
