* In          buildIndex(Database db)  the part that includes all fields from all tables partly works. For example a term in the db table user exists in the idex (as grep returns results, ) but cannot be found by the lucene search.
   * Also if the part that includes specifically only the gene, is excluded , the search of terms that exist in the index cannot be found. *
 * Same problem on ontocat search , terms are there but they cannot be found by lucene search
