added search index to full address field on mongodb
switched to case-sensitive search regexes (much faster than case insensitive, since it is able to take advantage of the index instead of ranging over every record)
limited number of search results to 7. this might not be ideal, but seems to help for now. potential future improvements: proper paging, some sort of indication of more results available
The corresponding API request for the address I was looking up works great: http://dev.api.bestnestapp.com/search?q=2011%20cooley
However, when I use the app front end it just appears to hang.
