Add the IK Chinese Word divider to the local Solr server for full-text retrieval.

In the previous article, we mentioned schema. the configuration of the <field/> element tag in xml. The tag has four attributes: name, type, indexed, and stored, this article describes how to search Chinese word segmentation by setting the value of the type attribute.

 

First download IK Chinese Word Segmentation project, https://code.google.com/archive/p/ik-analyzer/downloads? Page = 1,
　　
Besides the jar package, there are three related configuration files.
　　
Step 1: Add IKAnalyzer2012FF_u1.jar to the project's WEB-INF \ lib directory
　　
Step 2: Add IKAnalyzer. cfg. xml and stopword. dic to the classes directory of the project.
　　
You can manually configure the extended dictionary in the ext. dic file. In the IKAnalyzer. cfg. xml configuration file, we can see the corresponding configuration.
<? Xml version = "1.0" encoding = "UTF-8"?> <! DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd"> <properties> <comment> IK Analyzer Extension Configuration </comment> <! -- You can configure your own extended dictionary here --> <entry key = "ext_dict"> ext. dic; </entry> <! -- You can configure your own extended stopword dictionary here --> <entry key = "ext_stopwords"> stopword. dic; </entry> </properties>
 
Step 3: configure the word segmentation type in the schema. xml file.
　　
<fieldType name="text_ik" class="solr.TextField">      <analyzer type="index" isMaxWordLength="false" class="org.wltea.analyzer.lucene.IKAnalyzer"/>      <analyzer type="query" isMaxWordLength="true" class="org.wltea.analyzer.lucene.IKAnalyzer"/>   </fieldType>

After the configuration is complete, start the local service and perform word segmentation test on the Analysis menu page.

 

In this way, we can perform word segmentation search by setting the type attribute value to the name value of fieldType when customizing a field.

Record the other two tags used in schema. xml, uniqueKey and solrQueryParser.

• UniqueKey is used to set the primary key name. The default value is id.

•  

• SolrQueryParser is used to set the query conditions and or for fields during word segmentation. The default value is or and is commented out. When it is and, the field must contain the entered keywords for word segmentation, all data can be matched successfully.

•
