我已经遵循了至少12个不同的例子，所有这些看起来基本相同。我正在使用dse5.1和solr，并尝试使用suggester。以下是我的配置（主要是示例中的香草）：

<searchComponent name="suggest" class="solr.SuggestComponent">
     <lst name="suggester">
       <str name="name">titleSuggester</str>
       <str name="lookupImpl">AnalyzingInfixLookupFactory</str>
       <str name="dictionaryImpl">DocumentDictionaryFactory</str>
       <str name="suggestAnalyzerFieldType">TextField</str>
       <str name="field">title</str>
       <str name="weightField">rating</str>
       <str name="payloadField">description</str>
     </lst>
  </searchComponent>
  <requestHandler name="/suggest" class="solr.SearchHandler">
    <lst name="defaults">
      <str name="suggest">true</str>
      <str name="suggest.count">10</str>
    </lst>
    <arr name="components">
       <str>suggest</str>
    </arr>
  </requestHandler>

当我尝试在本地主机上运行curl来访问它时，我得到：

message Unknown command 'suggest' in request
   description Access to the specified resource has been forbidden

下面是curl命令：

curl --user myuser:mypass \
 "http://localhost:8983/solr/test.movies/suggest?suggest=true&suggest.dictionary=titleSuggester&suggest.q=Po"

我一辈子都搞不懂为什么我的实现不起作用。有什么想法吗？

我无法准确地再现这个问题-当我使用 FSTLookupFactory 实现时，dse 5.1.11抛出nullpointerexception。但我让它和 AnalyzingInfixLookupFactory 实现和以下配置：

<searchComponent class="solr.SuggestComponent" name="suggest">
    <lst name="suggester">
      <str name="name">titleSuggester</str>
      <str name="lookupImpl">AnalyzingInfixLookupFactory</str>
      <str name="dictionaryImpl">DocumentDictionaryFactory</str>
      <str name="suggestAnalyzerFieldType">TextField</str>
      <str name="field">title</str>
      <str name="weightField">rating</str>
      <str name="buildOnCommit">true</str>
      <str name="exactMatchFirst">true</str>
      <str name="payloadField">description</str>
    </lst>
  </searchComponent>

它是由以下cql生成的（比使用xml文件更好）：

CREATE SEARCH INDEX ON test.movies WITH OPTIONS { reindex : false };
ALTER SEARCH INDEX SCHEMA ON test.movies SET field[@name='title']@type='StrField';
ALTER SEARCH INDEX SCHEMA ON test.movies SET field[@name='description']@type='TextField';

// create suggestion component & corresponding request handler.
ALTER SEARCH INDEX CONFIG ON test.movies ADD searchComponent[@name='suggest',@class='solr.SuggestComponent'] 
WITH  $$ {"suggester":[{"name":"titleSuggester"}, {"lookupImpl":"AnalyzingInfixLookupFactory"}, {"dictionaryImpl":"DocumentDictionaryFactory"},
{"suggestAnalyzerFieldType":"TextField"}, {"field":"title"}, {"weightField":"rating"}, {"buildOnCommit":"true"}, {"exactMatchFirst":"true"}, {"payloadField": "description"}]} $$;
ALTER SEARCH INDEX CONFIG ON test.movies ADD requestHandler[@name='/suggest',@class='solr.SearchHandler'] 
WITH  $$ {"defaults":[{"suggest":"true"}, {"suggest.count":"10"}],"components":["suggest"]} $$;
RELOAD SEARCH INDEX ON test.movies;

它的工作原理是：

>curl 'http://localhost:8983/solr/test.movies/suggest?suggest=true&suggest.dictionary=titleSuggester&suggest.q=best&wt=json'
{"responseHeader":{"status":0,"QTime":1},
   "suggest":{"titleSuggester":{"best":{"numFound":1,
   "suggestions":[{"term":"the <b>best</b> movie","weight":1,
      "payload":"super movie"}]}}}}
