Adding analyzers

Elastic Stack Elasticsearch
1

Using these index settings:

{
"analysis":{
"analyzer":{
"title":{
"type":"standard"
},
"en_title":{
"type":"org.apache.lucene.analysis.en.EnglishAnalyzer"
},
"cjk_title":{
"type":"org.apache.lucene.analysis.cjk.CJKAnalyzer"
}
}
}
}

Causes this:

  1. Could not find a suitable constructor in
    org.apache.lucene.analysis.cjk.CJKAnalyzer. Classes must have either one
    (and only one) constructor annotated with @Inject or a zero-argument
    constructor that is not private.
    at org.apache.lucene.analysis.cjk.CJKAnalyzer.class(CJKAnalyzer.java:46)
    at
    org.elasticsearch.index.analysis.AnalyzerProviderFactory.create(AnalyzerProviderFactory.java:1)
    at
    org.elasticsearch.common.inject.assistedinject.FactoryProvider2.initialize(FactoryProvider2.java:161)
    at
    org.elasticsearch.index.analysis.AnalysisModule.configure(AnalysisModule.java:299)

  2. Could not find a suitable constructor in
    org.apache.lucene.analysis.en.EnglishAnalyzer. Classes must have either one
    (and only one) constructor annotated with @Inject or a zero-argument
    constructor that is not private.

    at
    org.elasticsearch.common.inject.assistedinject.FactoryProvider2.initialize(FactoryProvider2.java:161)
    at
    org.elasticsearch.index.analysis.AnalysisModule.configure(AnalysisModule.java:299)

I suppose I could just wrap the analyzers myself to make them work, but
thought I'd see what your suggestion may be.

Thanks.

Paul.

For custom analyzers, then you need to wrap it youself with an elasticsearch analyzer factory that creates them. But, those specific analyzers are already exposed in elasticsearch (the english on in 0.16.1, though its just a porter stemmer if memory serves).

I think you're correct about the PorterStemmer, however the SnowBallAnalyzer
is deprecated so don't know what option I have.

Its deprecated for the specific language analysis analyzers. In 0.16, you have cjk (for the CJKAnalyzer), and in upcoming 0.16.1 you also have english for the EnglishAnalyzer. cjk and english are similar to standard, you can just start using them in your mappings.
