搜索条件的怪异问题

[zhaoguobin]

我使用Redis::Search.complete搜索，如果搜索ab，附带搜索条件与不附带搜索条件，返回结果都正确。
如果搜索a，不附带搜索条件，结果正确，附带搜索条件，无结果（数据库中有符合的记录）。

怪哉！

实际的数据场景发出来看看

[zhaoguobin]

Model: User

字段：id, username, deleted_at

username数据：a1, a2, a3, b1, b2, b3, b4,c1,c2,c3,c4,abc 。。。  大致这些
deleted_at: 全部为 nil

Model 索引：
redis_search_index(
    :title_field => :username, 
    :prefix_index_enable => true,
    :condition_fields => [:deleted_at]
  )

开了pinyin

Redis::Search.complete("User","a")
结果正常

Redis::Search.complete("User","a", :conditions => {:deleted_at => nil})
[ ]

Redis::Search.complete("User","a1")
[{"title"=>"a1", "id"=>29, "type"=>"User", "deleted_at"=>nil}]

Redis::Search.complete("User","a1", :conditions => {:deleted_at => nil})
[{"title"=>"a1", "id"=>29, "type"=>"User", "deleted_at"=>nil}]

“a1”的都正确！

新法现：

“ta"是随手输入的

Redis::Search.complete("User","ta")
[ ]

Redis::Search.complete("User","ta", :conditions => {:deleted_at => nil})
结果返回了非常多的无关结果
