Hey guys, here is my query:  
{  
"query": {  
"bool": {  
"minimum\_should\_match": 1,  
"must": [],  
"must\_not": [],  
"should": [  
{  
"query\_string": {  
"fields": [  
"emailAddress"  
],  
"query": "test@abc.com"  
}  
}  
]  
}  
},  
"from": 0,  
"size": 25  
}

whenever I run this, I would also get back results that have emails that  
dont match [test@abc.com](mailto:test@abc.com), such as [hi@abc.com](mailto:hi@abc.com)

If i switch the field to names, the searches will come back exact.

Is there a special meaning to the @ sign that's doing this?

Thx
