IK如何实现同义词搜索

 

 

如何通过IK实现

 

<!--[if !supportLists]-->1、  <!--[endif]-->在schema.xml中配置

 

         <fieldType name="text_ik" class="solr.TextField" >

      <analyzer type="index"  >

             <tokenizer class="org.wltea.analyzer.lucene.IKTokenizerFactory"/>

                    <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />

         <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="false"/>    

      </analyzer>

            

      <analyzer type="query">

                   <tokenizer class="org.wltea.analyzer.lucene.IKTokenizerFactory"/>

                   <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />

        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>

      </analyzer>

            

    </fieldType>

 

 

<!--[if !supportLists]-->2、  <!--[endif]-->修改solr配置文件synonyms.txt

打开synonyms.txt文件，写如下内容，另存为utf-8文件，覆盖原来的synonyms.txt文件

#some test synonym mappings unlikely to appear in real input text

aaafoo => aaabar

bbbfoo => bbbfoo bbbbar

cccfoo => cccbar cccbaz

fooaaa,baraaa,bazaaa

 

# Some synonym groups specific to this example

GB,gib,gigabyte,gigabytes

MB,mib,megabyte,megabytes

Television, Televisions, TV, TVs

#notice we use "gib" instead of "GiB" so any WordDelimiterFilter coming

#after us won't split it into two words.

 

# Synonym mappings can be used for spelling correction too

pixima => pixma

康飞,飞飞,小飞,飞机

小人 => 男人 女人 认认 人人

<!--[if !supportLists]-->3、  <!--[endif]-->创建collection，进入analysis，做测试

<!--[endif]-->

 

 

 

<!--[if !supportLists]-->4、  <!--[endif]-->后期动态维护synonyms.txt的办法是，使用zookeeper管理工具，连接到zookeeper管理中心，找到synonyms.txt文件，修改，保存。
