Lucene 2.4.0 Range Query未按预期工作 [英] Lucene 2.4.0 Range Query is not working as expected

问题描述

以下是带值的索引字段：

  EffectiveDate =1970
 ExpirationDate =2035
  

创建索引和搜索的代码：

 public class IndexTest {
 
 static analyzer analyzer = new StandardAnalyzer（）; 
 static IndexSearcher isearcher; 
 
 @BeforeClass 
 public static void createIndex（）抛出CorruptIndexException，LockObtainFailedException，IOException {
 Store s = Field.Store.YES; 
 Store ds = Field.Store.YES; 
 Index IA = Field.Index.ANALYZED; 
 Index INA = Field.Index.NOT_ANALYZED; 
 
 IndexWriter iwriter = new IndexWriter（C：// tmp / testindex / sample，analyzer，true）; 
 iwriter.setMaxFieldLength（25000）; 
 
 //示例dummy文档
 Document doc = new Document（）; 
 Document doc1 = new Document（）; 
 Document doc2 = new Document（）; 
 Document doc3 = new Document（）; 
 
 doc.add（新字段（EffectiveDate，1970，ds，IA））; 
 doc.add（新字段（ExpirationDate，2035，ds，IA））; 
 
 iwriter.addDocument（doc）; 
 $ b $ doc1.add（新字段（EffectiveDate，1970，ds，IA））; 
 doc1.add（新字段（ExpirationDate，2035，ds，IA））; 
 
 iwriter.addDocument（doc1）; 
 
 iwriter.optimize（）; 
 iwriter.close（）; 
 
 $ b @Test 
 public void testRangeQuery（）抛出java.text.ParseException，Exception，IOException {
 
 
 isearcher = new IndexSearcher的（ E：// TMP / testindex /样品）; 
 
 // String rQuery =EffectiveDate：[* TO 1971]; 
 // String rQuery =EffectiveDate：[1960 TO 2000]; 
 // String rQuery =ExpirationDate：[2000 TO 2050]; 
 
 
 //以下查询不起作用
字符串rQuery =ExpirationDate：[2000 TO *]; 
 
 MultiFieldQueryParser parser = new MultiFieldQueryParser（
 new String [] {
EffectiveDate
，ExpirationDate}，analyzer）; 
 //parser.setDefaultOperator(QueryParser.Operator.OR）; 
 parser.setAllowLeadingWildcard（true）; 
查询查询= parser.parse（rQuery）; 
 System.out.println（Str =+ rQuery）; 
 System.out.println（query =+ query）; 
 Hits hits = isearcher.search（query）; 
 assertEquals（2，hits.length（））; 
 for（int i = 0; i< hits.length（）; i ++）{
 Document hitDoc = hits.doc（i）; 
 System.out.println（hitDoc =+ hitDoc）; 
 System.out.println（hitDoc.get（Code））; 
} 
 System.out.println（1query =+ query）; 
 
 
 
 
 
 
 
逻辑： - 当前日期应该在这两个字段之间。 
 
 
 
下面的范围查询工作正常： -  
  EffectiveDate：[* TO 2013-06-26] 
  
 低于范围查询无效： -   
  ExpirationDate：[2013-06-26 TO *] 
  
 任何帮助都是非常可观的。提前感谢      解决方案
 
下面的范围查询解决了我的问题：
 
 
 
 ExpirationDate：[2013-06-26 TO null] 
 
Below are the indexed fields with value:
 EffectiveDate="1970"
 ExpirationDate="2035"
Code to create index and seach:
public class IndexTest{

static Analyzer analyzer = new StandardAnalyzer();
static IndexSearcher isearcher;

@BeforeClass
public static void createIndex() throws CorruptIndexException, LockObtainFailedException, IOException{
    Store s = Field.Store.YES;
    Store ds = Field.Store.YES;
    Index IA = Field.Index.ANALYZED;
    Index INA = Field.Index.NOT_ANALYZED;

    IndexWriter iwriter = new IndexWriter("C://tmp/testindex/sample", analyzer, true);
    iwriter.setMaxFieldLength(25000);

    //Sample dummy docs
    Document doc = new Document();
    Document doc1 = new Document();
    Document doc2 = new Document();
    Document doc3 = new Document();

    doc.add(new Field("EffectiveDate", "1970", ds, IA));
    doc.add(new Field("ExpirationDate", "2035", ds, IA));

    iwriter.addDocument(doc);

    doc1.add(new Field("EffectiveDate", "1970", ds, IA));
    doc1.add(new Field("ExpirationDate", "2035", ds, IA));

    iwriter.addDocument(doc1);

    iwriter.optimize();
    iwriter.close();
}

   @Test
public void testRangeQuery() throws java.text.ParseException, Exception, IOException{


    isearcher = new IndexSearcher("E://tmp/testindex/sample");

       // String rQuery = " EffectiveDate : [* TO 1971 ]"; 
           // String rQuery = " EffectiveDate : [1960 TO 2000]"; 
           // String rQuery = " ExpirationDate : [2000 TO 2050]"; 


           //Below Query is Not Working
           String rQuery = " ExpirationDate : [2000 TO *]"; 

    MultiFieldQueryParser parser = new MultiFieldQueryParser(
              new String[] { 
                 "EffectiveDate"
                 ,"ExpirationDate"}, analyzer);
        //parser.setDefaultOperator(QueryParser.Operator.OR);
        parser.setAllowLeadingWildcard(true);
        Query query = parser.parse(rQuery);
        System.out.println("Str = "+rQuery);
        System.out.println("query = "+query);
        Hits hits = isearcher.search(query);
        assertEquals(2, hits.length());
        for (int i = 0; i < hits.length(); i++) {
            Document hitDoc = hits.doc(i);
            System.out.println("hitDoc = "+hitDoc);
            System.out.println(hitDoc.get("Code"));
        }
     System.out.println("1query = "+query);

}
Logic :- current date should be between these two field.

Below Range query is working:-
EffectiveDate : [ * TO 2013-06-26 ]
Below Range query is not working:-
ExpirationDate : [2013-06-26 TO *] 
Any help would be highly appreciable.Thanks in advance
解决方案
Below Range Query Solved my problem:-

ExpirationDate : [2013-06-26 TO null]
