使用solr建议程序时显示以下错误。有没有人遇到类似的错误。是由于查找工厂限制导致的错误。

最佳答案
我也遇到了同样的问题:一个客户要求我在装有Solr 5.5.0、1个核心/节点,500k +文档的Win2008计算机上激活建议程序模块。
我认为StackOverflowError是由于某些 FuzzyLookupFactory 实现而导致的,当它必须从头开始构建大型Lookup Data Structure时,该实现无法正常工作。
我无法使Fuzzy建议程序与FuzzyLookupFactory一起使用,在这种情况下,对我而言,唯一的解决方案是使用 FreeTextLookupFactory 将其激活。
我发布了我的配置文件的摘录,希望对您有所帮助:
solrconfig.xml
<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">mySuggester</str>
<str name="lookupImpl">FreeTextLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">content</str>
<str name="suggestFreeTextAnalyzerFieldType">suggestTypeLc</str>
<str name="buildOnStartup">true</str>
<str name="buildOnCommit">false</str>
</lst>
</searchComponent>
<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<str name="suggest">true</str>
<str name="suggest.count">10</str>
<str name="suggest.dictionary">mySuggester</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>

<fieldType name="suggestTypeLc" class="solr.TextField" positionIncrementGap="100">
<analyzer>
<charFilter class="solr.PatternReplaceCharFilterFactory" pattern="[^a-zA-Z0-9]" replacement=" " />
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>

在我的配置中,这通常需要几分钟才能完成。在不进行强制构建的情况下进行后续查询仅需几毫秒。 关于java - Solr的建议者抛出StackOverflow错误,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/33749956/
