solr5.3的spellcheck功能

1.增加schema.xml中的检查字段。

<field name="title" type="text_cn" indexed="true" stored="true" required="false" multiValued="false" /> <fieldType name="text_cn" class="solr.TextField"> <analyzer type="index"> <!--使用HanLP分析器进行分词 --> <tokenizer class="com.hankcs.lucene.HanLPTokenizerFactory" mode="max-word"/> <!-- 将分词结果同时转换为拼音 --> <filter class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory" minTermLenght="2" /> <filter class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory" minGram="6" maxGram="20" /> </analyzer> <analyzer type="query"> <tokenizer class="com.hankcs.lucene.HanLPTokenizerFactory" mode="max-word"/> <filter class="com.hankcs.lucene.analysis.synonym.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true" format="word2vec"/> <filter class="com.shentong.search.analyzers.PinyinTransformTokenFilterFactory" minTermLenght="2" /> <filter class="com.shentong.search.analyzers.PinyinNGramTokenFilterFactory" minGram="6" maxGram="20" /> </analyzer> </fieldType>

 

2.修改solrconfig.xml内容：

<searchComponent name="spellcheck" class="solr.SpellCheckComponent"> <!--<str name="queryAnalyzerFieldType">text_cn</str> --> <!-- a spellchecker built from a field of the main index --> <lst name="spellchecker"> <str name="name">default</str> <!--这里指明需要根据哪个字段的索引为依据进行拼写检查。现配置 名为 spell 的字段--> <str name="field">title</str> <str name="classname">solr.DirectSolrSpellChecker</str> <str name="distanceMeasure">internal</str> <float name="accuracy">0.5</float> <int name="maxEdits">2</int> <int name="minPrefix">1</int> <int name="maxInspections">5</int> <int name="minQueryLength">2</int> <float name="maxQueryFrequency">0.01</float> </lst> </searchComponent> <requestHandler name="/spell" class="solr.SearchHandler" startup="lazy"> <!--默认参数--> <lst name="defaults"> <str name="df">title</str> <str name="spellcheck.dictionary">default</str> <str name="spellcheck">true</str> <!-- <str name="spellcheck.extendedResults">true</str> <str name="spellcheck.count">10</str> <str name="spellcheck.alternativeTermCount">5</str> <str name="spellcheck.maxResultsForSuggest">5</str> --> <str name="spellcheck.collate">true</str> <str name="spellcheck.collateExtendedResults">true</str> <!-- <str name="spellcheck.maxCollationTries">10</str> <str name="spellcheck.maxCollations">5</str> --> </lst> <arr name="last-components"> <str>spellcheck</str> </arr> </requestHandler>

3.重新创建索引使其生效.

PS:参考了另一位博主的文章http://blog.youkuaiyun.com/kevinxxw/article/details/49708311 用的分词器不一样，另外增加了针对拼音的智能纠错
