如何在单个Solr建议程序中配置多个contextfields? [英] How to configure multiple contextfields in single solr suggester?

问题描述

我正在使用apache solr搜索当前应用程序中的记录.

I am using apache solr to search records in my current application.

通过配置上下文字段，我能够根据DocumentType过滤建议.

And I was able to filter the suggesions based on DocumentType by configuring the context field.

现在我想添加另一个上下文字段，例如departmentType.我不确定如何为多个上下文字段配置建议程序.

Now I want to add another context field like departmentType. I am not sure how to configure the suggester for multiple context fields.

这是与单个上下文字段一起使用的建议程序，它工作正常.

This is the suggester that used with single context fields and this is working fine.

 <searchComponent name="suggest" class="solr.SuggestComponent">
  <lst name="suggester">
     <str name="name">suggesterByName</str>
     <str name="lookupImpl">AnalyzingInfixLookupFactory</str>
     <str name="dictionaryImpl">DocumentDictionaryFactory</str>
     <str name="field">fullName</str>
     <str name="contextField">documentType</str>
        <str name="suggestAnalyzerFieldType">text_general</str>
     <str name="buildOnStartup">false</str>
   </lst>
 </searchComponent>

我推荐这篇文章 https://issues.apache.org/jira/browse/SOLR-7888

但仍不清楚如何在单个建议程序中配置多个上下文字段.

but still not clear how to configure multiple context fields in a single suggester .

推荐答案

您必须在schema.xml中创建一个新字段作为context_field. 此字段应具有multivalued=true

You have to create a new field in your schema.xml as context_field. This field should have multivalued=true

<field name="context_field" type="text_suggest" multiValued="true" indexed="true" stored="true"/>

然后，您必须在json中创建此context_field作为列表，以便在solr中建立索引.

Then you have to create this context_field as a list in json for indexing in solr.

"context_field" : ["some document type", "some department type"]

建立索引后，您可以像这样建议

after indexing you can suggest like this-

suggest.q=b&suggest.cfq=context_documentType AND context_departmentType
