SOLR - PathHierarchyTokenizerFactory Facet 查询

发布于 2024-11-28 02:56:40 字数 749 浏览 1 评论 0原文

我一直在尝试对配置为 solr.PathHierarchyTokenizerFactory 的字段执行查询，但查询仅返回所有记录。看来进行方面查询是行不通的。有没有人有办法实现这个？我正在使用 PathHierarchy 来实现类别/子类别方面。

<fieldType name="text_path" class="solr.TextField" positionIncrementGap="100">
    <analyzer>
        <tokenizer class="solr.PathHierarchyTokenizerFactory" delimiter="/" />
    </analyzer>
</fieldType>

<field name="libraries" type="text_path" indexed="true" stored="true" multiValued="true" />

和

http://linux2:8984/solr/select?q=*:*&rows=0&fq=libraries:"/test/subtest"&facet=true&facet.field=libraries&f .libraries.facet.sort=true&f.libraries.facet.limit=-1&f.libraries.facet.mincount=-1

谢谢

I have been trying to perform a query on a field that is configured to be solr.PathHierarchyTokenizerFactory, but the query just returns all records. It seems that doing a facet query is just not working. Does anyone have a way of accomplishing this? I'm using the PathHierarchy to implement category/subcategory facets.

<fieldType name="text_path" class="solr.TextField" positionIncrementGap="100">
    <analyzer>
        <tokenizer class="solr.PathHierarchyTokenizerFactory" delimiter="/" />
    </analyzer>
</fieldType>

<field name="libraries" type="text_path" indexed="true" stored="true" multiValued="true" />

And

http://linux2:8984/solr/select?q=*:*&rows=0&fq=libraries:"/test/subtest"&facet=true&facet.field=libraries&f.libraries.facet.sort=true&f.libraries.facet.limit=-1&f.libraries.facet.mincount=-1

Thanks

更改您的 text_path 字段定义以仅在索引时应用 PathHierarchyTokenizerFactory （下面的示例）。您的问题是您的查询正在由标记生成器处理，以便 fq=libraries:"/test/subtest" 实际上针对 fq=libraries:(/test/subtest OR /test) 进行查询。

<fieldType name="text_path" class="solr.TextField" positionIncrementGap="100">
    <analyzer type="index">
        <tokenizer class="solr.PathHierarchyTokenizerFactory" delimiter="/" />
    </analyzer>
</fieldType>

注意分析器类型=“索引”

Change your text_path field definition to apply the PathHierarchyTokenizerFactory at index time only (example below). Your issue is that your queries are being processed by the tokenizer so that fq=libraries:"/test/subtest" actually queries against fq=libraries:(/test/subtest OR /test).

<fieldType name="text_path" class="solr.TextField" positionIncrementGap="100">
    <analyzer type="index">
        <tokenizer class="solr.PathHierarchyTokenizerFactory" delimiter="/" />
    </analyzer>
</fieldType>

Note the analyzer type="Index"
