Searching Instagram? go to
http://statigr.am the search will allow searching for one tag at a time many user join what would be single words together in a group or phrase without any spaces. You can sometime find these by searching for the first part of the phrase. So instead of searching for peeinginthewoods you could seaarch for peeinin you then get a list of all the tags that start with this phrase peeinginpublic with 333 photo's peeiningthewoods 81 photo's and peeinginthepool 81 photo's.You can the click on the link and jumpoff to one of the other tags. You will never see the number of the photos they say are in the tag as some people do not allow access to the public. Some searches will fail as the word is blocked, like boobs but b00bs works so be devious...
These are the tags I have used, the number of pictures using the tag at the last time I visited it, also some useful comments.
