I thought entering a term would bring up the appropriate keywords from the list that's present below it (irregardless of word order: a search for "dragon" would bring up "bearded dragon" and "dragon".
From what I can gather the search only targets the first word in keywords, so you can not target the second word in a keyword. Which seems problematic if you are searching for someone by last name. Also, searching is case sensitive. Can this be changed?
Also, I think it would be handy if when you search it populated the list of keywords that match that search as opposed to only circling it with a box. If I need to put that in the feature request forum I can.
