I know as of right now the search API does not return any user location information but I am just wondering exactly how some apps manage to gather this info. I'm looking specifically at http://micro.ilist.com/. It looks like this app simply tracks hash tags and I would assume they are caching their results in some sort of db. If they were making a separate request this would put them way over the api limit, obviously unless they have gained extra access.
I am currently developing an app that sends 4 search API calls every 15 mins. My results are stored in a db, where I can apply a bit of "magic" to them to help weed out some of the spam. The one huge piece of data missing here would be location. Are there any methods available that won't completely kill my api limit?
