Question

使用6.0.1 SOLR。有一个类型声明：

 <fieldType name="customy_icu" class="solr.TextField" positionIncrementGap="100">
         <analyzer type="index">
            <tokenizer class="solr.ICUTokenizerFactory"/>
            <filter class="solr.LengthFilterFactory" min="1" max="100"/>
            <filter class="solr.NGramTokenizerFactory" minGramSize="2" maxGramSize="20"/>
            <filter class="solr.LowerCaseFilterFactory"/>
         </analyzer>
         <analyzer type="query">
            <tokenizer class="solr.ICUTokenizerFactory"/>
            <filter class="solr.LengthFilterFactory" min="1" max="100"/>
            <filter class="solr.LowerCaseFilterFactory"/>
         </analyzer>
      </fieldType>

customy_icu用于从右到左存储希伯来语（单词正在读/写）的文本数据。

当查询是“מיפנים”时我得到的结果是错误的顺序，product_3351比产品product_3407更高（更相关），但反之亦然。这是debug：

 <str name="product_3351">

和

  <str name="product_3407">

  2.711071 = max of:
    2.711071 = weight(name:"מי פנים" in 919) [ClassicSimilarity], result of:

如何在结果列表中提升3407产品？

非常感谢！

Answer 1

如果您要将特定查询提升到结果集的顶部，与其自己的分数无关，请使用Query Elevation Component。

没有自动提升＃34;出现在文档的前面＃34;但是有几种方法可以解决它。有关几种可能的解决方案，请参阅How to boost scores for early matches。

＆＃34;相关性＆＃34;这是一个流利的术语，您必须在标准规则之外实现您认为适合您的应用程序的那种评分。您已包含的debugQuery显示默认情况下文档的相关性评分相同。

Answer 2

您可以使用elevate.xml文件将特定文档设置为特定serachterm的结果集中的顶部。

示例：

<elevate>
<query text ="מי פנים">
<doc id="your_product_ID" />
</query>
