Hi everyone

I'm have index with such data

{"id": "some\_id",  
"owner\_id": "some\_owner\_id",  
"created": "{some\_creation\_date}",  
"tag": "some\_tag",  
"fields":{  
{"first\_name": "michael",  
"last\_name":"girnyak",  
"name":"michael girnyak",  
"phone": "66666666"}  
}  
{"id": "some\_id",  
"owner\_id": "some\_owner\_id",  
"created": "{some\_creation\_date}",  
"tag": "some\_tag",  
"fields":{  
"first\_name": "anton",  
"last\_name": "koval",  
"name": "anton koval",  
"phone": "5555555"}  
}  
{"id": "some\_id",  
"owner\_id": "some\_owner\_id",  
"created": "{some\_creation\_date}",  
"tag": "some\_tag",  
"fields":{  
{"first\_name": "brenda",  
"last\_name":"cristin",  
"name":"brenda cristin",  
"phone": "77777777"}  
}  
with mapping such as  
{  
"contact": {  
"\_all" : { "enabled" : False },  
"\_source" : { "enabled" : False },  
"properties" : {  
"id": {  
"type": "string",  
"store": "yes"  
},  
"owner\_id": {  
"type": "string",  
"index": "not\_analyzed",  
},  
"created": {  
"type": "date",  
"index": "not\_analyzed",  
"format" : "yyyy-MM-dd'T'HH:mm:ssZ"  
},  
"tag":{  
"type": "string",  
"index": "not\_analyzed",  
"omit\_term\_freq\_and\_positions": "true",  
},  
"fields": {  
"type": "object",  
"properties" : {  
"first\_name": {  
"type": "string",  
"index": "not\_analyzed",  
"omit\_term\_freq\_and\_positions": "true"  
},  
"last\_name": {  
"type": "string",  
"index": "not\_analyzed",  
"omit\_term\_freq\_and\_positions": "true"  
},  
"name": {  
"type": "string",  
"index": "not\_analyzed",  
"omit\_term\_freq\_and\_positions": "true"  
},  
"phone":  
"type": "string",  
"index": "not\_analyzed",  
"omit\_term\_freq\_and\_positions": "true"  
},  
}  
}  
}

and try search by wildcard  
{"query": {"wildcard": {"fields.first\_name": "_a_"}}}  
I want to have results in this direction  
first item with first\_name Anton  
second item with first\_name michAel  
third item with first\_name brendA  
the search criteria must go from start of first\_name field to end

what I need to do to get such results?  
maybe I need to use some analyzer or some specific boosting  
please help me with this I will be very appreciate

All wildcard matches return the score: 1.

If you want to use relevancy with partial matches, then you should look  
at using the ngram or edge-ngram analyzers

What actually I need to do? Could you explain me? Or may you give me some  
example?  
I try nGram analyzer but it don't give an results for me, the score is still  
same for each of index data item. =((
