Field configured to be filtered with LowerCaseFilterFactory?

I have a brand name field that is configured to be tokenized as a keyword and lowercased:

Code:

@AnalyzerDef(name="name_analyzer", tokenizer = @TokenizerDef(factory = KeywordTokenizerFactory.class), filters=[@TokenFilterDef(factory = LowerCaseFilterFactory.class)])
class Make {
    @Field(index = Index.UN_TOKENIZED, store = Store.YES)
    @Analyzer(definition="name_analyzer")
    String name
}

But when I look at the index with Luke, names are not lowercased. So when I query "caterpillar" instead of "Caterpillar", I can't find instances whose name is "Caterpillar".

What did I do wrong?

Hi,

you need to tokenize the input or at least use the option _index = Index.TOKENIZED_. This will then trigger the use of your tokenizer/analyzer chain. Given that you are using a keyword tokenizer your input will not be broken up either way (only lowercased).
