The real purpose for including a hashtag is that they give you and other tweeters an easy way to search for a particular topic due to the fact that hashtags act as a kind of natural filter.Here is how to perform a hashtag search on the Advanced Search page:
• In the “This Hashtag” text box, type in the hashtag topic you want to find. (Do not add the hashtag symbol yet, Twitter does that automatically)
• Click Search
Although Hashtag searching is easiest from the Search box because Edwin Urrutia all you have to do is place the hashtag (#) in front of the topic. For example if you search “#windows7 )” then the results will include posts with “windows 7 )”.
Searching for Tweets by Location
If you use Twitter on your mobile phone and if it includes a global positioning system (GPS) sensor, chances are that the client will post your location along with your update. That way the tweets you send are tagged with your current position, so many Twitter updates have an associated location.
If you are interested in locating people who are tweeting near a particular location, you can use Twitter Search to specify that location and distance. For example, you can search for tweets sent within 25 miles of Lawrenceville, Georgia.
Here are 4 steps to search for tweets by location using the Advanced Search page
1. In the “Near this Place” text box, type location.
2. Use the “Within this Distance” list to select value. Choices are 1, 5, 10, 15, 25, 50, 100, 500, or 1000.
3. Select either Miles or Kilometers
4. Click Search.
To do the same procedure but in the Search box, simply add two operators
• Near use this operator followed by place name to search for tweets sent from that location
• Within use this operator followed by a number followed by either mi (for miles) or km (for kilometers) to search for tweets within that distance of location.
Example: McDonalds nearAtlanta within10mi
One big advantage you get by using these operators is that you can use them on their own. Meaning, using “near” on its own shows all the posts sent from just that location. Using “within” on its own shows all the posts sent within the specified distance of current location.
