dse solr建议者状态403-未知命令“建议”

Question

我至少跟踪了十二个不同的示例，所有这些示例看起来几乎都是相同的。我正在使用DSE 5.1和SOLR并尝试使用建议程序。这是我的配置（大部分来自示例）：

  <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>

当我尝试运行curl在本地主机上访问它时，我得到：

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

这是curl命令：

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

无法弄清楚我的一生为什么我的实现无法正常工作。有什么想法吗？

Answer 1

我无法完全重现此问题-当我使用FSTLookupFactory实现时，DSE 5.1.11抛出NullPointerException。但是我使它可以与AnalyzingInfixLookupFactory实现并遵循以下配置一起使用：

  <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>

通过遵循CQL生成的

（比使用XML文件更可取）：

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;

它有效：

>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"}]}}}}
