Examples of org.apache.lucene.search.TermQuery

org.apache.lucene.search.TermQuery
A Query that matches documents containing a term. This may be combined with other terms with a {@link BooleanQuery}.

      value = String.valueOf(condition.getValue());


    String fieldname = String.valueOf(condition.getField().getId());


    Term term = new Term(fieldname, value);
    return new TermQuery(term);
