lucene 范围搜索表达式(range expression)

实际测试

lucene范围符号，大于等于或小于等于符号[]，大于或小于符号{}

 

newIntRange或newLongRange一样

 

 

代码：

          // test lucene expression

          BooleanQuery bQuery = new BooleanQuery();

         

          // test range expression

         

          // +LPUBLISHTIME1:{1 TO 3}

          NumericRangeQuery numRangeQuery1 = NumericRangeQuery.newIntRange("lpublishtime1".toUpperCase(), 1, 3, false, false);

          bQuery.add(numRangeQuery1, BooleanClause.Occur.MUST);

          System.out.println(bQuery);

         

          // +LPUBLISHTIME2:[1 TO 3}

          NumericRangeQuery numRangeQuery2 = NumericRangeQuery.newIntRange("lpublishtime2".toUpperCase(), 1, 3, true, false);

          bQuery.add(numRangeQuery2, BooleanClause.Occur.MUST);

          System.out.println(bQuery);

         

          // +LPUBLISHTIME2:[1 TO 3]

          NumericRangeQuery numRangeQuery3 = NumericRangeQuery.newIntRange("lpublishtime2".toUpperCase(), 1, 3, true, true);

          bQuery.add(numRangeQuery3, BooleanClause.Occur.MUST);

          System.out.println(bQuery);
