我有一个可搜索的域类映射到具有标志列的表。目前,当 Lucene 创建索引时,它会生成这样的查询(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

是否可以仅为那些包含特定标志值的行构建索引,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

是的,我认为你可以做到这一点。以下是伪代码。

   Document doc = new Document();
doc.add(Field.Text("flag", Y));
