Question

我的solr索引中存有一些视频标题。我根据标题查询，但想要评分来影响分数。该评级是典型的5星评级。此评级与视频一起存储在solr中。我尝试使用dismax请求处理程序，但看起来solr没有提升值。

您可以在下面看到我的requestHandler：

<requestHandler default="true" name="dismax" class="solr.SearchHandler" >
<lst name="dismax">
 <str name="defType">dismax</str>
 <str name="echoParams">explicit</str>
 <float name="tie">0.01</float>
 <str name="qf">
    title
 </str>
 <str name="pf">
    title
 </str>
 <str name="mm">
    0
 </str>
 <str name="bq">
    rating:1^1.0 rating:2^1.0 rating:3^3.0 rating:4^5.0 rating:5^10.0
 </str>
 <str name="fl">
    *,score
 </str>
 <int name="ps">100</int>
 <str name="q.alt">*:*</str>
</lst>

希望有人可以帮助我！

我使用debug运行查询，这是调试的输出。在计算得分时看不到评分字段......

4.429465 = (MATCH) weight(title:test in 1894), product of:
0.99999994 = queryWeight（title：test），产品：4.4294653 = idf（docFreq = 26876，maxDocs = 829428）0.22576088 = queryNorm 4.4294653 = （MATCH）fieldWeight（标题：1894年测试），产品：1.0 = tf（termFreq（title：test）= 1）4.4294653 = idf（docFreq = 26876， maxDocs = 829428）1.0 = fieldNorm（field = title，doc = 1894）

更多调试信息：

<lst name="debug">
<str name="rawquerystring">test</str>
<str name="querystring">test</str>
<str name="parsedquery">title:test</str>
<str name="parsedquery_toString">title:test</str>

似乎您已将列表定义为dismax而非默认值 -

<requestHandler name="dismax" class="solr.SearchHandler" >
    <lst name="defaults">
        <str name="defType">dismax</str>
        <str name="echoParams">explicit</str>
        <float name="tie">0.01</float>
        <str name="qf">
            title
        </str>
        <str name="pf">
            title
        </str>
        <str name="mm">
            0
        </str>
        <str name="bq">
            rating:1^1.0 rating:2^1.0 rating:3^3.0 rating:4^5.0 rating:5^10.0
        </str>
        <str name="fl">
            *,score
        </str>
        <int name="ps">100</int>
        <str name="q.alt">*:*</str>
    </lst>
</requestHandler>

对我来说很好 -

<str name="parsedquery">(+DisjunctionMaxQuery((title:itunes)~0.01) DisjunctionMaxQuery((title:itunes)~0.01) rating:1 rating:2 rating:3^3.0 rating:4^5.0 rating:5^10.0)/no_coord</str>

Solr dismax提升查询不起作用
