There are techniques for full text search in DB, but frankly I never used them.
Now, there is already room for improvement.
General advise is to avoid SELECT * in favor of selecting only the needed fields. I don't see the point of getting q if you don't use it.
Also you should avoid using append(), which is slow. Just use an array list.
Note: bad idea to use o as loop variable, it looks too much like a 0.

solved this by changing the database to fullText, but i don't trust the results....
i'm reading it from an external PHP file now...

some snippets:
sending to PHP file

1. ..... 
   
2. String textPerson2 =  textPerson.replace(',', ' ');
         String textPerson3 =  textPerson2.replace('.', ' ');
         String textPerson4 = textPerson3.replace('(', ' ');
         String textPerson5  = textPerson4.replace(')', ' ');
         String textPerson6 = textPerson5.replace('?', ' ');
         String textPerson7 = textPerson6.replace('!', ' ');
         String textPerson8 = textPerson7.replace('-', ' ');
         String textPerson9 = textPerson8.replaceAll(" "," ");
         String textPerson10 = textPerson9.replaceAll("'"," ");
         String textPerson11 = textPerson10.replace(' ', ' ');
         String textPerson12 = textPerson11.replace('"', ' ');
         String dateEnd1 = dateEnd.replaceAll(" "," ");
         String dateBegin1 = dateBegin.replaceAll(" "," ");  // making the text clean and replacing the spaces with to get it tru
          println(textPerson12);
         
         String result[]=loadStrings("http://localhost/redactioneel/word-counter"+lang+".php?textPerson="+textPerson12+"&dateBegin="+dateBegin1+"&dateEnd="+dateEnd1);
        
         String[] listResult = split(result[0], "NEXTRESULTS"); // getting the results back and split them
         String[] listWords = split(listResult[0], " " );
         println(listWords);
         String[] listCount = split(listResult[1], " ");
         String   listCountJoinString = join(listWords, ", ");
         listCountJoin = append(listCountJoin, listCountJoinString);

receiving file:

1. $word = array();
   $count = array();
   $dateBegin = $_GET['dateBegin'];
   $dateEnd = $_GET['dateEnd'];
   $textPerson = $_GET['textPerson'];
   $textPersonExplode = explode(" ", $textPerson );
   $db = dbConnect();
    $query = "SELECT word, count(word) FROM news_google_split WHERE MATCH(word) AGAINST ('$textPerson') AND date >= '$dateBegin' AND date <= '$dateEnd' GROUP BY word"; 
   $result = mysql_query($query) or die(mysql_error());
   
   
   
   while($row = mysql_fetch_array($result, MYSQL_ASSOC))
   {
    $word[] = $row["word"];
    $count[] = $row["count(word)"];
   }
   if (!$result) {
       die('Invalid query: ' . mysql_error());
   }
   dbClose($db);
   for ( $counter = 0;$counter <= sizeof($word) ; $counter++) {
      echo $word[$counter];
      echo " ";  
   }
   echo "NEXTRESULTS";
   for ( $counter = 0;$counter <= sizeof($count) ; $counter++) {
     echo $count[$counter];
      echo " ";    
   }
         
   

If somebody knows a better way.. would be nice to hear it. Maybe a way  for Processing to pass tru an array better.
