Hi all! I have read in the api documentation that we can set a specific analyzers fir a document by setting the "\_analyzer" property in the mapping like this: { "type1" : { "\_analyzer" : { "path" : "my\_field" } } } so if I set the analyzer I want to use a specific analyzer dor a document, I have to set the value of "my\_field" to its name. I tried this for my cas, but it does not seem to work so my mapping is : {"content": { "\_source" : {"enabled" : true}, "\_uid" : {"index" : "no", "store" : "no"}, "\_id" : {"index" : "no", "store" : "yes"}, "\_analyzer" : {"path" : "my\_anal", "index" : "no"}, "\_index" : {"enabled" : true, "index" : "no", "store" : "yes"}, "properties" : { "body" : {"type" : "string", "store" : "yes", ``` "index" : "analyzed", "boost" : 1.0, "term_vector" : "with_positions_offsets" }} ``` }. The documents I index are like this: {"body" : "some data here", "my\_anal" : "french-analyzer"} where 'french-analyzer' is an anlyzer I defined in the settings So! what is wrong wth my settings?? ---

I don't see anything particular wrong with your settings. Are you getting an error? If not, why do you think that something is wrong? Can you make sure that mappings are applied correctly by running curl -XGET localhost:9200/your-index/\_mapping Are specifying proper analyzer for your search queries?

Yes! the mapping is correctly applied. There is no error in the search but it seems that the stemming is not well running. My analyzer is correctly configured since when I set it statically, it works fine.

Could you post a repro to clarify what you mean by "stemming is not well running". Here is an example to get you started: [Specific analyzer per document repro ยท GitHub](https://gist.github.com/2358376) On Wednesday, April 11, 2012 3:28:33 AM UTC-4, lyes zaiko wrote: > Yes! the mapping is correctly applied.
