[twitter-dev] Re: Suggested method for getting GEO results
I am building a RSS native mobile app that pull Twitter feeds using Search API. I am experiencing similar behavior. Sometimes it has fewer results. Could you advise me? If I would have to use Twitter to report real- time events such as Earthquake alerts? for Medical Emergency alerts? Should I use Search API for reliable real time results? Or consider Stream API? Other questions relating to using Geo and Places. - What is the best way to filter results to just cover tweets from US? Do I use a central geo point in US like mid west and expand the radius? - Would Near: & Within: filter deliver the same results as Geo filter? example earthquake near:US within:500mi? Would near: filter work on country level? - How could I find acceptable country name that use in near: filter? example Africa, Haiti? - What is the radius limit on Geo & Near? in terms of mi or km? - Do you recommend any utility or tools that I can export public tweets into data store? for reporting purposes Note: I try to expand geo radius to 800 miles but couldn't get much results.

Re: [twitter-dev] Re: Suggested method for getting GEO results
As Taylor said, the Streaming API sounds like it would be a good option for you to consider but for a user driven search like yours you would probably need to build a caching layer. Whilst the near operator works well on the search.twitter.com website it isn't supported through the search API. Unfortunately this means you won't be able to use that operator in the way you hope to. I am interested in the blank results you get though and wondered if you would be happy to answer a couple of questions for me: * Do you ever see an error or warning in the response? * Are you using since_id? * Can you give an example of just one of your queries?

[twitter-dev] Re: Suggested method for getting GEO results
thanks Taylor for the reply. I am referring to user-initiated queries. We have users that type in a keyword to a search box, and we then return results from the Search API with the corresponding Geo Coordinates included with the request On Jun 2, 5:51 pm, Taylor Singletary wrote: > Have you considered using the Streaming API for this > purpose?http://apiwiki.twitter.com/Streaming-API-Documentation#locations-- we > encourage those with heavy search needs to use it as an alternative.
