Twitter4j search

Hi

I've got twitter4j working on a streaming basis - e.g. to capture live tweets as they come in (by hashtag). Is there a way instead to just do a once off search by hashtag?

Current code below

import twitter4j.*;
import twitter4j.api.*;
import twitter4j.auth.*;
import twitter4j.conf.*;
import twitter4j.json.*;
import twitter4j.management.*;
import twitter4j.util.*;
import twitter4j.util.function.*;

static String OAuthConsumerKey = "";   
static String OAuthConsumerSecret = "";   
static String AccessToken = "";
static String AccessTokenSecret = "";


String keywords[] = {"#processing"};


void setup(){

  ConfigurationBuilder cb = new ConfigurationBuilder();

  cb.setOAuthConsumerKey(OAuthConsumerKey);
  cb.setOAuthConsumerSecret(OAuthConsumerSecret);
  cb.setOAuthAccessToken(AccessToken);
  cb.setOAuthAccessTokenSecret(AccessTokenSecret);

  TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance();

  twitterStream.addListener(listener);
  size(200, 200);


  if (keywords.length==0){
    twitterStream.sample();
  }
  else{
    twitterStream.filter(new FilterQuery().track(keywords));
  }
}

void draw() {

  }


StatusListener listener = new StatusListener(){
  public void onStatus(Status status){
    String tweet = status.getText();
    String user = "@" + status.getUser().getScreenName();
    tweet = user + " - " + tweet;
    println(tweet);
  }
  public void onDeletionNotice(StatusDeletionNotice statusDeletionNotice) {
    //System.out.println("Got a status deletion notice id:" + statusDeletionNotice.getStatusId());
  }
  public void onTrackLimitationNotice(int numberOfLimitedStatuses) {
    //  System.out.println("Got track limitation notice:" + numberOfLimitedStatuses);
  }
  public void onScrubGeo(long userId, long upToStatusId) {
    System.out.println("Got scrub_geo event userId:" + userId + " upToStatusId:" + upToStatusId);
  }

  public void onException(Exception ex) {
    ex.printStackTrace();
  }
  public void onStallWarning(StallWarning warning){

  }
};
