I am able to extract tweets of a specific hashtag using the search method like below
twitter4j.Twitter twitter = TwitterFactory.getSingleton();
Query query = new Query("ipl7");
QueryResult result = twitter.search(query);
for (Status status : result.getTweets()) {
System.out.println("@" + status.getUser().getScreenName() + " : " + status.getText() + " : " + status.getGeoLocation());
}
But, I got very limited number of tweets using the above method. what should I change to get all the tweets of a specific hashtag?
You can use streaming API to get the recent tweets by a given set of keywords. In your case you have only one keyword which is a hashtag, right? I posted a brief sample code to search tweets by a keyword with Streaming API. You can use both Streaming and Search API for different purposes. Mostly you can use Search API for the hostorical tweets up to a limited time. It allows you to give a date interval. However, you can use Streamin API to catch the recently posted tweets as a tweet stream that contains the keywords that you give.
Example straming code below:
private static void GetTweetStreamForKeywords()
{
TwitterStream twitterStream = new TwitterStreamFactory(config).getInstance();
StatusListener statusListener = new StatusListener() {
@Override
public void onStatus(Status status) {
// The main section that you get the tweet. You can access it by status object.
// You can save it in a database table.
}
@Override
public void onDeletionNotice(StatusDeletionNotice sdn) {
throw new UnsupportedOperationException("Not supported yet.");
}
@Override
public void onTrackLimitationNotice(int i) {
throw new UnsupportedOperationException("Not supported yet.");
}
@Override
public void onScrubGeo(long l, long l1) {
throw new UnsupportedOperationException("Not supported yet.");
}
@Override
public void onStallWarning(StallWarning sw) {
throw new UnsupportedOperationException("Not supported yet.");
}
@Override
public void onException(Exception ex) {
logWriter.WriteErrorLog(ex, "onException()");
}
};
FilterQuery fq = new FilterQuery();
String keywords[] = {"sport", "politics", "health"};
fq.track(keywords);
twitterStream.addListener(statusListener);
twitterStream.filter(fq);
}

while (tweets.size () < numberOfTweets) {
if (numberOfTweets - tweets.size() > 100)
query.setCount(100);
else
query.setCount(numberOfTweets - tweets.size());
try {
QueryResult result = twitter.search(query);
tweets.addAll(result.getTweets());
System.out.println("Gathered " + tweets.size() + " tweets"+"\n");
for (Status t: tweets)
if(t.getId() < lastID)
lastID = t.getId();
}
catch (TwitterException te) {
System.out.println("Couldn't connect: " + te);
};
query.setMaxId(lastID-1);
}
for (int i = 0; i < tweets.size(); i++) {
Status t = (Status) tweets.get(i);
// GeoLocation loc = t.getGeoLocation();
String user = t.getUser().getScreenName();
String msg = t.getText();
//String time = "";
//if (loc!=null) {
//Double lat = t.getGeoLocation().getLatitude();
//Double lon = t.getGeoLocation().getLongitude();*/
System.out. println(i + " USER: " + user + " wrote: " + msg + "\n");
}
//else
//System.out.println(i + " USER: " + user + " wrote: " + msg+"\n");
}
}
Use the count(int resultCount) method :
Query query = new Query("ipl7");
query.count(100); //100 is the max allowed
QueryResult result = twitter.search(query);
