Hi all,

I have issues understanding my config and/or search.

I have an index created with : (curl)  
{  
"settings": {  
"index" : {  
"analysis" : {  
"analyzer" : {  
"french\_analyzer" : {  
"tokenizer" : "standard",  
"filter" : ["standard", "lowercase",  
"french\_stemmer"]  
}  
},  
"filter" : {  
"french\_stemmer" : {  
"type" : "stemmer",  
"name" : "french"  
}  
}  
}  
}  
}  
}

and after mapping is added also via curl with :  
{  
"article":  
{  
"\_all":  
{  
"enabled" : true  
},  
"\_analyzer" : {  
"default" : {  
"type" : "french\_analyzer"  
}  
},  
"properties":  
{  
"id":  
{  
"type":"long",  
"index": "no",  
"store":"no"  
},  
"slug":  
{  
"type":"string",  
"index": "not\_analyzed",  
"store":"no"  
},  
"code":  
{  
"type":"string",  
"index": "not\_analyzed",  
"store":"yes",  
"boost": 5.0  
},  
"name":  
{  
"type":"string",  
"index": "analyzed",  
"store":"yes",  
"boost": 5.0,  
"analyzer" : "french\_analyzer"  
},  
"active":  
{  
"type":"boolean",  
"index": "no",  
"store":"yes"  
},  
"suggest":  
{  
"type" :"completion",  
"index\_analyzer" : "simple",  
"search\_analyzer" : "simple"  
}  
}  
}  
}

Datas are indexed via bulk file

I am trying to do a query\_string search on x fields (not all analyzed by  
the stemmer).  
curl -XGET 'localhost:9200/quableindex\_fr\_fr/\_search?pretty=true' -d '{  
"query": {  
"query\_string": {  
"query": "encastrée",  
"fields": [  
"description",  
"name"  
],  
"analyzer" : "french\_analyzer"  
}  
},  
"sort": {  
"\_score": {  
"order": "desc"  
}  
},  
"explain": false  
}'

This is working ie. "encastrée", "encastrable" and "encastrer" are shown as  
results. (all from name field)  
But if I do not use the analyzer line in the query\_string, french stemmer  
seems not to be used (while it has been setted in mapping)  
curl -XGET 'localhost:9200/quableindex\_fr\_fr/\_search?pretty=true' -d '{  
"query": {  
"query\_string": {  
"query": "encastrée",  
"fields": [  
"description",  
"name"  
]  
}  
},  
"explain": false  
}'

Could anyone explain me ? I think I missed something.

Thanks.

Sylvain
