Question

我有以下带注释的类搜索功能（不完整，只是试图让它立即工作）：

我试图得到它，以便当用户搜索“foo ba”时，结果将弹出包含'foo bar'，'foo bat'等的行，但是这些术语显示在同一个字段中。 I.E.如果标题为“foo”且ID为“bat”，则不会显示，而标题为“foo bath”的行将显示。现在，如果即使其中一个单词出现在任何字段中，它也会被返回，并且排序根本不起作用（但这是下一步所以我现在对此并不那么担心）。 / p>

修正了它，结果我忘了在第一个词中添加到搜索XD

实际查询文本：FullTextQueryImpl（jobTitle：“entry（architect artist）”）

修正了所有内容的代码更改：

...........

      Term firstTerm = new Term("jobTitle", "entry");
    **  Term secondTerm = firstTerm.createTerm("ar");

      Term[] tTerms = new Term[] { firstTerm, secondTerm };
      MultiPhraseQuery multiPhrasequery = new MultiPhraseQuery();

      try {
         File index = new File("I:/com.rhc.rayport.model.JobReq");
         Directory indexDirectory = FSDirectory.open(index); 
         System.out.println(indexDirectory);
         PrefixTermEnum reader = new PrefixTermEnum(IndexReader.open(indexDirectory), secondTerm);
         System.out.println(reader.toString());

         List<Term> termList = new LinkedList<Term>();
         while (reader.docFreq() != -1) {
               Term t = reader.term();
               System.out.println(t);
            if (t.field().equals("jobTitle") ||  t.text().startsWith(secondTerm.text())) {
                termList.add(t);
            }
           reader.next();              
         }

         Term[] terms = termList.toArray(new Term[0]);
         multiPhrasequery.add(firstTerm);
       **  multiPhrasequery.add(terms);

Hibernate外卡短语搜索结果不是最优的
