Hey,

I'm curious about the difference between specifying a search\_analyzer on a field and specifying an analyzer in a query\_string call to the API. My indication is that they are the same. So, if my mapping looks like the following:  
...  
"mapping": {  
"boost": 1.0,  
'index': 'analyzed',  
'store': 'yes',  
"type": "multi\_field",  
"fields": {  
"{name}": {"type": "{dynamic\_type}"},  
"ngram": {  
"include\_in\_all": False,  
"index\_analyzer": "ngram",  
"search\_analyzer": "standard",  
"type": "string"  
},  
"edgengram": {  
"include\_in\_all": False,  
"index\_analyzer": "edgengram",  
"search\_analyzer": "standard",  
"type": "string"  
},  
"snowball": {  
"include\_in\_all": False,  
"analyzer": "snowball",  
"type": "string"  
}  
}

then my custom fields will be analyzed by my custom analyzers, and a search query will be analyzed by the standard analyzer?
