Ikanalyzer is used in solr4.9 to implement synonyms, expand the dictionary, and add pause words.

When solr4.9 is used, ikanalyzer is used, which has encountered many problems. Now we need to make a record for later use.

First, ikanalyzer is used to see some people in the group, but it seems that no one has updated ikanalyzer... I don't know if it is true. Let's ignore this. Next we will introduce how to use it in SOLR.

In the SOLR configuration file schema. XML, add

<!--IKAnalyzer-->   <fieldType name="text_ik" class="solr.TextField" positionIncrementGap="100">       <analyzer type="index">         <tokenizer class="org.wltea.analyzer.lucene.IKAnalyzerSolrFactory"  isMaxWordLength="false"/>         <filter class="solr.LowerCaseFilterFactory"/>       </analyzer>       <analyzer type="query">         <tokenizer class="org.wltea.analyzer.lucene.IKAnalyzerSolrFactory"  isMaxWordLength="true"/>              <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>         <filter class="solr.LowerCaseFilterFactory"/>       </analyzer>     </fieldType>

Here, the org. wltea. analyzer. Lucene. ikanalyzersolrfactory class is self-extended. I will upload ikanalyzer to the jar package later.

Synonyms.txt is in the solr_home/Didi/CONF file.

Configure extension words and extension pause words:

The content of ikanalyzer. cfg. XML is as follows:

<? 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 <Entry key = "ext_dict"> Ext. dic; </entry> --> <Entry key = "ext_dict"> mydict. dic; </entry> <! -- You can configure your own extended stopword dictionary here --> <Entry key = "ext_stopwords"> stopword. DIC; </entry> </Properties>
