lucene4.x how to filter a field ?

Field publish is StringField type , add the following method of the field

  doc.add(new StringField("publish", publish, Field.Store.YES));
  

now have to solve is how to filter the field , such as search out the results only publish = " microblogging " result.
How can I do ?

I tried IndexSearcher 's search methods used FieldValueFilter or TermsFilter class , it seems we can not do .

------ Solution --------------------------------- -----------
IndexSearcher + Query query directly on the line , do not Filter.

          try {
              FSDirectory fsdir = FSDirectory.open(new File("索引路径"));
              IndexReader reader = DirectoryReader.open(fsdir);
              fsdir.close();
              IndexSearcher searcher = new IndexSearcher(reader);
              Query query = new TermQuery(new Term("publish", "微博"));
              ScoreDoc[] hits = searcher.search(query, 5000).scoreDocs;
              int size = hits.length;
              for (int i = 0; i < size; i++) {
                  Document doc = searcher.doc(hits[i].doc);
                  System.out.println(doc.get("publish"));
              }
          } catch (IOException ex) {
              ex.printStackTrace(System.err);
          }
