Question

我对pellic类型的spell字段刻面有问题。我遇到了一个Exception during facet.field: spell异常，并且不确定是否可以实际使用此字段。

Solr版本：6.6.5

请求标头：

GET /solr/core_de/select?facet.field=spell&facet=on&indent=on&q=*:*&wt=json HTTP/1.1
Host: xxxx:8983

Solr请求处理程序：

<requestHandler name="/select" class="solr.SearchHandler">
    <lst name="defaults">
        <str name="defType">edismax</str>
        <str name="echoParams">explicit</str>
        <str name="qf">content^40.0 title^5.0 keywords^2.0 tagsH1^5.0 tagsH2H3^3.0 tagsH4H5H6^2.0 tagsInline^1.0</str>
        <str name="pf">content^2.0</str>
        <str name="df">content</str>
        <int name="ps">15</int>

        <str name="mm">2&lt;-35%</str>
        <str name="mm.autoRelax">true</str>

        <str name="hl.fl">title,content</str>
        <int name="hl.snippets">3</int>
        <str name="hl.mergeContiguous">true</str>
        <str name="hl.requireFieldMatch">true</str>

        <str name="f.content.hl.alternateField">content</str>
        <str name="f.content.hl.maxAlternateFieldLength">200</str>

        <str name="spellcheck">false</str>
        <str name="spellcheck.onlyMorePopular">false</str>
        <str name="spellcheck.extendedResults">false</str>
        <str name="spellcheck.count">1</str>
        <str name="spellcheck.dictionary">default</str>
        <str name="spellcheck.dictionary">wordbreak</str>

        <str name="wt">json</str>
        <str name="indent">true</str>
    </lst>

    <arr name="last-components">
        <str>spellcheck</str>
        <str>elevator</str>
    </arr>
</requestHandler>

solrconfig.xml中的拼写检查searchComponent

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
    <str name="queryAnalyzerFieldType">textSpell</str>

    <lst name="spellchecker">
        <str name="name">default</str>
        <str name="field">spell</str>
        <str name="classname">solr.DirectSolrSpellChecker</str>
        <str name="distanceMeasure">internal</str>
        <float name="accuracy">0.5</float>
        <int name="maxEdits">2</int>
        <int name="minPrefix">1</int>
        <int name="maxInspections">5</int>
        <int name="minQueryLength">3</int>
        <float name="maxQueryFrequency">0.01</float>
    </lst>

    <!-- a spellchecker that can break or combine words.  See "/spell" handler below for usage -->
    <lst name="spellchecker">
        <str name="name">wordbreak</str>
        <str name="classname">solr.WordBreakSolrSpellChecker</str>
        <str name="field">spell</str>
    </lst>
</searchComponent>

general_schema_fields.xml中的字段定义

<field name="spell" type="textSpell" indexed="true" stored="false" multiValued="true" />
<copyField source="title"    dest="spell" />
<copyField source="subTitle" dest="spell" />
<copyField source="content"  dest="spell" />

从solr源代码开始，该过程在以下位置引发异常：

https://github.com/apache/lucene-solr/blob/releases/lucene-solr/6.6.5/solr/core/src/java/org/apache/solr/request/SimpleFacets.java#L809

该异常的前几行：

tat org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:582)
tat org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143)

克服标题等字段的问题是没有问题的。

我如何使其工作？

谢谢。
