示例1: test

import org.apache.lucene.search.spans.MultiSpansWrapper; //導入依賴的package包/類
public void test() throws IOException {
  PayloadTermQuery query = new PayloadTermQuery(new Term("field", "seventy"),
          new MaxPayloadFunction());
  TopDocs hits = searcher.search(query, null, 100);
  assertTrue("hits is null and it shouldn't be", hits != null);
  assertTrue("hits Size: " + hits.totalHits + " is not: " + 100, hits.totalHits == 100);

  //they should all have the exact same score, because they all contain seventy once, and we set
  //all the other similarity factors to be 1
