Hi, Does the analyze API ( [http://www.elasticsearch.org/guide/reference/api/admin-indices-analyze.html](http://www.elasticsearch.org/guide/reference/api/admin-indices-analyze.html)) support the char\_filter ? I tried curl -XGET 'localhost:9200/\_analyze?tokenizer=keyword&filters=lowercase&char\_filter=myCharFilter' -d 'this is a test' and curl -XGET 'localhost:9200/\_analyze?tokenizer=keyword&filters=lowercase&char\_filters=myCharFilter' -d 'this is a test' without success.

I have never tried a custom filter, but with analyzers, they will only work if you are analyze against an index that is using them. The analyzer would need to be loaded/instantiated first before it can be used, and that only occurs when an index that uses the analyzer (in the mapping) is created. I would assume filters have the same limitation.

Looks like the \_analyze endpoint only supports token filters. I don't see a way to pass in char filters.

Ha, didn't think that would be the limitation! Shouldn't be too hard to add in. The eventual consumer, TransportAnalyzeAction, is just using an empty char filter array.
