> I've fixed most of the issues you have brought up in this ticket. > However, the query dealing with the vector indexes I have left alone > for now. The person that originally wrote this part of the code has > been gone for a while now, but it looks like the way the index is > created is completely incorrect e.g., > > Given a vector such as [abcdefgh] with a word length of 2, the > *correct* words should be: > [ab] [bc] [cd] [de] [ef] [fg] [gh] > > not > > [ab] [cd] [ef] [gh] > > Also, these words need to be stored composed with the index position, > in the same field (See > http://download.pureftpd.org/pub/pure-ftpd/misc/libpuzzle/doc/README > for more technical detail if interested). > > Combine this with the fact that the images that are being compared > are very small (just the face portion), and the current query really > has very little chance of finding a similar face, unless it almost > the exact same image - after that, it's just pure luck. > > This should be fixed before Ansel 2.0
