To get access to the Twitter public stream, you need a developer account to obtain OAuth credentials. After creating an account on the Twitter developer site, you can obtain these credentials by creating an "application". After you've created an application, create an access token by clicking on the button "Create my access token".
To to run the Twitter (near) real-time search demo, you must save your Twitter API OAuth credentials in a file named twitter4j.properties in your current working directory. See this page for more information about Twitter4j configurations. The file should contain the following (replace the ********** instances with your information):
oauth.consumerKey=**********
oauth.consumerSecret=**********
oauth.accessToken=**********
oauth.accessTokenSecret=**********
Once you've done that, fire up the demo with:
sh target/appassembler/bin/TweetSearcher -index twitter-index
The demo starts up an HTTP server on port 8080, but this can be changed with the -port option. Query via a web browser at http://localhost:8080/search?query=query. Try birthday, as there are always birthdays being celebrated.
User could change the maximum number of hits returned at 'http://localhost:8080/search?query=birthday&top=15'. The default number of hits is 20.
