4.5.4. @AnalyzerDef for Solr

When using Maven all required Apache Solr dependencies are now defined as dependencies of the artifact org.hibernate:hibernate-search-analyzers. Add the following dependency: 
<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-search-analyzers</artifactId>
   <version>${version.hibernate.search}</version>
<dependency>

In the following example, a CharFilter is defined by its factory. In this example, a mapping char filter is used, which will replace characters in the input based on the rules specified in the mapping file. Finally, a list of filters is defined by their factories. In this example, the StopFilter filter is built reading the dedicated words property file. The filter will ignore case.

Procedure 4.2. @AnalyzerDef and the Solr framework

  1. Configure the CharFilter

    Define a CharFilter by factory. In this example, a mapping CharFilter is used, which will replace characters in the input based on the rules specified in the mapping file. 
    @AnalyzerDef(name="customanalyzer",
  charFilters = {
    @CharFilterDef(factory = MappingCharFilterFactory.class, params = {
      @Parameter(name = "mapping",
        value = "org/hibernate/search/test/analyzer/solr/mapping-chars.properties")
    })
  },
    Copy to Clipboard Toggle word wrap

  2. Define the Tokenizer

    A Tokenizer is then defined using the StandardTokenizerFactory.class. 
    @AnalyzerDef(name="customanalyzer",
  charFilters = {
    @CharFilterDef(factory = MappingCharFilterFactory.class, params = {
      @Parameter(name = "mapping",
        value = "org/hibernate/search/test/analyzer/solr/mapping-chars.properties")
    })
  },
  
  tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class)

  3. List of Filters

    Define a list of filters by their factories. In this example, the StopFilter filter is built reading the dedicated words property file. The filter will ignore case. 
    @AnalyzerDef(name="customanalyzer",
  charFilters = {
    @CharFilterDef(factory = MappingCharFilterFactory.class, params = {
      @Parameter(name = "mapping",
        value = "org/hibernate/search/test/analyzer/solr/mapping-chars.properties")
    })
  },
  
  tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class),
  filters = {
                 
    @TokenFilterDef(factory = ISOLatin1AccentFilterFactory.class),
    @TokenFilterDef(factory = LowerCaseFilterFactory.class),
    @TokenFilterDef(factory = StopFilterFactory.class, params = {
      @Parameter(name="words",
        value= "org/hibernate/search/test/analyzer/solr/stoplist.properties" ),
      @Parameter(name="ignoreCase", value="true")
    })
})public class Team {
    ...}

Note

Filters and CharFilters are applied in the order they are defined in the @AnalyzerDef annotation.
