solr4.7 Chinese word breaker (ik-analyzer) configuration

SOLR itself on the Chinese word processing is not too good, so the Chinese application often need to add a Chinese word breaker to Chinese word processing, Ik-analyzer is one of the good Chinese word breaker.

First, version information

SOLR version: 4.7.0

Requires Ik-analyzer version: IK Analyzer 2012ff_hf1

Ik-analyzer Download Address: http://code.google.com/p/ik-analyzer/downloads/list

Second, the configuration steps

Download the compressed Extract folder after extracting the following directory structure:

We copy the Ikanalyzer2012ff_u1.jar to the Solr\web-inf\lib under the SOLR service.

We copy the IKAnalyzer.cfg.xml and Stopword.dic to the Conf of the core that needs to use the word breaker, and a directory for the core Schema.xml file.

To modify the schema.xml of the core, add the following configuration between the <types></types> configuration items:

<fieldtype name= "Text_ik" class= "SOLR. TextField "> 
     <analyzer class=" Org.wltea.analyzer.lucene.IKAnalyzer "/> 
</fieldType>

We've got a Text_ik field type, and the word breaker used by this type is Ik-analyzer.

We can use Text_ik when we configure the field type in the schema.xml of this core.

<field name= "name"      type= "Text_ik"   indexed= "true"  stored= "true"
