Lucene如何实现多条件搜索？

有两种方式可以实现，

一是：Lucene搜索API中提供了一个布尔查询器（BooleanQuery），它可以包含多个查询器，每个查询器Occur枚举控制是“and” 还是“or”

BooleanQuery.Builder booleanQueryBuilder = new BooleanQuery.Builder(); Query query1 = NumericRangeQuery.newIntRange("cid", 1, 2, true, true); Query query2 = NumericRangeQuery.newLongRange("price", 1000L, 2000L, true, true);   booleanQueryBuilder.add(query1, Occur.SHOULD);//Occur.MUST(和查询),Occur.SHOULD(或查询),Occur.MUST_NOT(异查询) booleanQueryBuilder.add(query2, Occur.MUST); Query query = booleanQueryBuilder.build();

二是：利用QueryParser解析一个多条件语法搜索查询器

QueryParser queryParser = new QueryParser("*", analyzer); Query query = queryParser.parse("name:'手机' AND brand:'小米'");
