在我的铁路应用程序中, 我有一个问题模型, 由太阳日落软体设置, 带有字段“ 文本 ”, 我想在这个字段中搜索一个逻辑 OR 。 我发现, 将最小匹配到 1 解决了我的问题, 但我也想通过添加匹配超过 1 个单词的问题来命令结果 。 有办法用 Sorr 来做到这一点吗? 文档对于排序函数没有多大帮助 。
编辑: 这是在控制器中执行的完整查询 I
@questions = Question.solr_search do
fulltext params[:query], :minimum_match => 1
end.results
根据
The default operator used by Solr s query parser (SolrQueryParser) can be configured with
<solrQueryParser defaultOperator="AND|OR"/>.
The default operator is "OR" if unspecified. It is preferable to not use or rely on this setting; instead the request handler or query LocalParams should specify the default operator. This setting here can be omitted and it is being considered for deprecation.
您可以在 solr/conf/schema.xml 中更改您的默认操作器, 或者您可以使用本地Params 来指定 OR, 如 < a href="https://github.com/sunspot/sunspot/sunpot/sunpot/ building- queries- by- hand
这是真实的太阳点默认操作员是“AND”,如 https://github.com/sunspot/sunspot/sunspot/blob/master/sunspot_solr/solr/solr/conf/schema.xml" rel=“nofollow”>https://github.com/sunspot/sunspot/blob/master/sunspot_solr/solr/solr/conf/schema.xml 中所提到的。
逻辑 OR 是 Sunspot 中使用的 Dismax 请求处理器的默认行为 。
加上,单词匹配越多,文档的评分越高(这听起来像你想要的)
Question.search do
fulltext best pizza
end
...应该返回匹配一个词或两个词的结果( 返回两个词都匹配的结果) :
minim_match 只有在想要过滤低相关性结果(其中只有一定的低数量或百分比的术语实际匹配)时才有用。 这不影响评分或逻辑的OR/AND行为。
