Hi,

you need to set the property _hibernate.search.analyzer_ to the fully qualified classname of your custom analyzer.

Hi,

in the properties file you can only specify a single analyzer class. If you want it to delegate to other analyzer you need a scoped analyzer (per field analyzer) which delegates to the appropriate analyzer based on the field name passed to the methods of the Analyzer interface. Have a look at the Hibernate Search internal class ScopedAnalyzer.

Thx Hardy.
how can i create a custom analyzer ??
for example
Code:
@AnalyzerDef(name = "simpleAnalyser", tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class), filters = {

        @TokenFilterDef(factory = StandardFilterFactory.class),
        @TokenFilterDef(factory = LowerCaseFilterFactory.class),
        @TokenFilterDef(factory = SnowballPorterFilterFactory.class, params = @Parameter(name = "language", value = "French"))
})

Thx :)

Hi,

you would have to programmatically wire together the analyzers. Look at the code for the different factories to get a feel how this is done. This is a fair bit of boiler plate code. For this reason we offer @AnalyzerDef. It just makes this process easier :-)

Hi,

look here - http://wiki.apache.org/lucene-java/Luce ... nalyzer.3F
Or even better look at these XYZFactory classes for example.
If you want all the gory details get hold of a copy of "Lucene in Action". Bottom line is that you have to understand how the analysis process works in Lucene and how tokenizers and filters work together.
