lucene实现 在某一范围进行搜索 RangeQuery

RangeQuery query = new RangeQuery(beginTime, endTime, false); 最后一个参数表示是否包含本身

书上的完整例子如下:

import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.index.Term;
import org.apache.lucene.search.Hits;
import org.apache.lucene.search.IndexSearcher;
import org.apache.lucene.search.RangeQuery;

public class RangeQueryTest {
public static void main (String [] args) throws Exception {
Document doc1 = new Document();
doc1.add(Field.Text("time", "200001"));
doc1.add(Field.Keyword("title", "doc1"));

Document doc2 = new Document();
doc2.add(Field.Text("time", "200002"));
doc2.add(Field.Keyword("title", "doc2"));

Document doc3 = new Document();
doc3.add(Field.Text("time", "200003"));
doc3.add(Field.Keyword("title", "doc3"));

Document doc4 = new Document();
doc4.add(Field.Text("time", "200004"));
doc4.add(Field.Keyword("title", "doc4"));

Document doc5 = new Document();
doc5.add(Field.Text("time", "200005"));
doc5.add(Field.Keyword("title", "doc5"));

IndexWriter writer = new IndexWriter("c://index", new StandardAnalyzer(), true);
writer.setUseCompoundFile(true);
writer.addDocument(doc1);
writer.addDocument(doc2);
writer.addDocument(doc3);
writer.addDocument(doc4);
writer.addDocument(doc5);
writer.close();

IndexSearcher searcher = new IndexSearcher("c://index");
Term beginTime = new Term("time","200001");
Term endTime = new Term("time","200005");

Hits hits = null;
RangeQuery query = null;

query = new RangeQuery(beginTime, endTime, false);
hits = searcher.search(query);
printResult(hits, "从200001到200005的文档，不包括200001和200005");

query = new RangeQuery(beginTime, endTime, true);
hits = searcher.search(query);
printResult(hits, "从200001到200005的文档，包括200001和200005");

}

public static void printResult(Hits hits, String key) throws Exception {
System.out.println("查找 /"" + key + "/" :");
if (hits != null) {
if (hits.length() == 0) {
System.out.println("没有找到任何结果");
} else {
System.out.print("找到");
for (int i = 0; i < hits.length(); i++) {
Document d = hits.doc(i);
String dname = d.get("title");
System.out.print(dname + " " );
}
System.out.println();
System.out.println();
}
}
}
}
