表的一部分的Lucene Grails可搜索插件構建索引

Question

我有一個可搜索的域類，映射到具有標志列的表。 當前，Lucene創建索引時，它會生成如下查詢（返回表中的所有數據）：

        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

是否可以僅為包含特定標志值的那些行構建索引，以便生成的查詢如下所示：

    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

Answer 1

是的，我認為您可以做到。 以下是偽代碼。

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