问题描述
我使用Solr的5.1。我想配置根据 Apache Solr实现维基在Solr搜索组件多个suggester定义
我已经完全配置单suggester和它的作品完美，但每当我试图配置多个suggester它给了我下面的错误

解决方案
谢谢您的回答@Dhanesh小号Radhakrishnar，你是正确的，但后来我们实际上改变的是AnalyzingInfixLookupFactory到FuzzyLookupFactory其作品，但我们的目的已经失去了。无论如何，我已经找到了解决方案，事情是这样的，我们需要增加分析仪的indexPath第二suggester的实施。 :)

I am using solr 5.1. I am trying to configure multiple suggester definition in Solr search component according to Apache solr wiki.
I have configured single suggester perfectly and it works perfect but whenever I try to configure multiple suggester it gives me following errors

解决方案
Thanks for your answer @Dhanesh S Radhakrishnar, You are right but then we are actually changing the AnalyzingInfixLookupFactory to FuzzyLookupFactory which works but our purpose has been lost. Anyhow i have found the solution and the thing is that, we need to add the indexPath of analyzer in the implementation of second suggester. :)
<searchComponent class="solr.SuggestComponent" name="suggest">
<lst name="suggester">
<str name="name">mySuggester</str>
<str name="lookupImpl">AnalyzingInfixLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">suggest_Manu</str> <!-- the indexed field to derive suggestions from -->
<str name="weightField">productId_meter</str>
<str name="suggestAnalyzerFieldType">suggestAnalyzer</str>
<str name="buildOnCommit">true</str>
</lst>
<lst name="suggester">
<str name="name">mySuggester2</str>
<str name="lookupImpl">AnalyzingInfixLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">suggest_Name</str> <!-- the indexed field to derive suggestions from -->
<str name="weightExpression">productId_meter</str>
<str name="suggestAnalyzerFieldType">suggestAnalyzer</str>
<str name="indexPath">path-of-system-dir/newSuggester2</str>
<str name="buildOnCommit">true</str>
</lst>
</searchComponent>
