In order to work around an issue where windows live photo gallery keeps losing my video metadata I have given all my videos long file names (eg 2015-01-01_Persons Name 1_Persons Name 2_Location_some_other_tags.mov)

Now in theory I can find what I want by searching for a persons name and have it match the filename, this works fine in windows explorer but will not work in Photo Gallery - it would be nice if it would work in photo gallery also.

To complicate things when I to a text search in photo gallery for movies with my daughters name I get 30 results returned - some from September 2012 and some from October 2013 - this is incredibly frustrating because I cannot figure out why these sets of videos are matched while nothing else is.
