I am presently working with language analyzer. In this I found that if we need to use the analyzer for searching documents then we need to define mapping along with analyzer.  
In my case, if document contains a normal text field this works fine but when I apply same property to a nested field then the analyzer is not working.

This is code for language analyzer

PUT checkmap  
{  
"settings": {  
"analysis" : {  
"analyzer" : {  
"stemmerenglish" : {  
"tokenizer" : "standard",  
"filter" : ["standard", "lowercase", "my\_stemmer"]  
}  
},  
"filter" : {  
"my\_stemmer" : {  
"type" : "stemmer",  
"name" : "english"  
}  
}  
}  
},  
"mappings": {  
"dd": {  
"properties": {  
"Courses": {  
"type" : "nested",  
"properties": {  
"Sname" : {  
"type" : "text",  
"analyzer": "stemmerenglish",  
"search\_analyzer": "stemmerenglish"  
}  
}  
}  
}  
}  
}  
}  
Please help me out with above problem.
