Analyze API + char_filter

Elastic Stack Elasticsearch
1

Hi,

Does the analyze API (
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.
Any idea ?

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.

Cheers,

Ivan

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.
