我有一个映射到具有标志列的表的可搜索域类。当前,Lucene创建索引时,它会生成如下查询(返回表中的所有数据):
select this_.id as id0_0_,
this_.flag as flag2_0_0_,
this_.email as email0_0_, this_.first_name as first6_0_0_, this_.last_name as last8_0_0_
from ais_person this_
order by this_.id asc
是否可以仅为包含特定标志值的那些行建立索引,以便生成的查询如下所示:
select this_.id as id0_0_,
this_.flag as flag2_0_0_,
this_.email as email0_0_, this_.first_name as first6_0_0_, this_.last_name as last8_0_0_
from ais_person this_
where this_.flag = 'Y'
order by this_.id asc
最佳答案
是的,我认为您可以做到。以下是伪代码。
Document doc = new Document();
doc.add(Field.Text("flag", Y));
