Solr的建议 - 如何定义Solr的建议不区分大小写

问题描述

我的建议（拼写检查）将返回区分大小写的答案。
（我用它来自动完成 - 狗与狗返回不同的短语）\\

我的建议定义如下 -
在solrconfig -

 ＆LT;的SearchComponent类=solr.SpellCheckComponentNAME =建议＆GT;
＆LT; LST NAME =拼写检查＆GT;
    ＆LT; STR名=名与GT;建议＆LT; / STR＆GT;
    ＆LT; STR NAME =类名＆GT; org.apache.solr.spelling.suggest.Suggester＆LT; / STR＆GT;
    ＆LT; STR NAME =lookupImpl＆GT; org.apache.solr.spelling.suggest.tst.TSTLookup＆LT; / STR＆GT;
    ＆LT; STR NAME =场＆GT;建议＆LT; / STR＆GT; ＆LT;！ - 索引字段从得到的建议 - ＆GT;
    ＆LT;浮动NAME =门槛＆GT; 0.005 LT; /浮动＆GT;
    ＆LT; STR NAME =buildOnCommit＆GT;真＆LT; / STR＆GT;
    ＆LT;！ - ＆LT; STR NAME =sourceLocation＆GT;美式英语和LT; / STR＆GT;  - ＆GT;
＆LT; / LST＆GT;
＆LT; /＆的SearchComponent GT;
＆LT; requestHandler类=org.apache.solr.handler.component.SearchHandlerNAME =/提示＆GT;
    ＆LT; LST NAME =默认＆GT;
        ＆LT; STR NAME =拼写检查＆GT;真＆LT; / STR＆GT;
        ＆LT; STR NAME =spellcheck.dictionary＆GT;建议＆LT; / STR＆GT;
        ＆LT; STR NAME =spellcheck.onlyMorePopular＆GT;真＆LT; / STR＆GT;
        ＆LT; STR NAME =spellcheck.count＆GT; 5℃/ STR＆GT;
        ＆LT; STR NAME =spellcheck.collat​​e＆GT;真＆LT; / STR＆GT;
    ＆LT; / LST＆GT;
    ＆LT; ARR NAME =组件＆GT;
        ＆LT; STR＆GT;建议＆LT; / STR＆GT;
    ＆LT; / ARR＆GT;
＆LT; / requestHandler＆GT;
 

在架构

 ＆LT;字段名=建议TYPE =phrase_suggest收录=真正的存储=真要求=假多值=真/＆GT;
 

和

 ＆LT; copyField源=姓名目标=建议/＆GT;
 

和

 ＆LT;字段类型名称=phrase_suggest级=solr.TextField＆GT;
  ＆LT;分析仪和GT;
    ＆LT; tokenizer类=solr.KeywordTokenizerFactory/＆GT;
    ＆LT;过滤器类=solr.PatternReplaceFilterFactory
            模式=（[^ \\ p {L〕\\ p {M-} \\ p {N} \\ p {铯}] * [\\ p {L〕\\ p {M-} \\ p {N} \\ p {铯} \\ _] + :) |（[^ \\ p {L〕\\ p {M-} \\ p {N} \\ p {}铯]）+
            更换=替换=所有/＆GT;
    ＆LT;过滤器类=solr.LowerCaseFilterFactory/＆GT;
    ＆LT;过滤器类=solr.TrimFilterFactory/＆GT;
  ＆LT; /分析仪＆GT;
＆LT; /字段类型＆GT;
 

解决方案

尝试改变它们添加到字段类型过滤器工厂的订单。此外，地方 LowerCaseFilterFactory 在列表的顶端。

My suggest (spellchecker) is returning case sensitive answers.(I use it to autocomplete - dog and Dog return different phrases)\

my suggest is defined as follows -in solrconfig -

 <searchComponent class="solr.SpellCheckComponent" name="suggest">
<lst name="spellchecker">
    <str name="name">suggest</str>
    <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
    <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
    <str name="field">suggest</str>  <!-- the indexed field to derive suggestions from -->
    <float name="threshold">0.005</float>
    <str name="buildOnCommit">true</str>
    <!--<str name="sourceLocation">american-english</str>-->
</lst>
</searchComponent>
<requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggest">
    <lst name="defaults">
        <str name="spellcheck">true</str>
        <str name="spellcheck.dictionary">suggest</str>
        <str name="spellcheck.onlyMorePopular">true</str>
        <str name="spellcheck.count">5</str>
        <str name="spellcheck.collate">true</str>
    </lst>
    <arr name="components">
        <str>suggest</str>
    </arr>
</requestHandler>

in schema

<field name="suggest" type="phrase_suggest" indexed="true" stored="true" required="false" multiValued="true"/>

and

<copyField source="Name" dest="suggest"/>

and

<fieldtype name="phrase_suggest" class="solr.TextField">
  <analyzer>
    <tokenizer class="solr.KeywordTokenizerFactory"/>
    <filter class="solr.PatternReplaceFilterFactory"
            pattern="([^\p{L}\p{M}\p{N}\p{Cs}]*[\p{L}\p{M}\p{N}\p{Cs}\_]+:)|([^\p{L}\p{M}\p{N}\p{Cs}])+"
            replacement=" " replace="all"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.TrimFilterFactory"/>
  </analyzer>
</fieldtype>

解决方案

Try to change the order of filter factories which are added into the fieldType. Also, place LowerCaseFilterFactory at the top of the list.
