Camel case search with Lucene

Hi friends,

How can I implement Camel case search with Lucene?

Thanks,
Ira

Could it be something with WordDelimiterFilter, EdgeNgram, and then
WordDelimiterFilter with CATENATE_ALL?

Hi Vadim,

I want to use camel case when searching, for example, search "RHC" and find "redHotChilly".

Thanks,
Ira

Hi Ira.

If you want to use camel case query, for example, search "redHotChilly"
instead of "red hot chilly" - you should use own pattern tokenizer to
divide the query by regex pattern.

Hi Ira.

If you want to use camel case query, for example, search "redHotChilly"
instead of "red hot chilly" - you should use own pattern tokenizer to
divide the query by regex pattern.
