Boost parameter is used in the below example  
wildcard": {  
"City": {  
"wildcard": "_M_",  
"boost": 10  
}  
Can I use similar query for weight?

What is the difference between apply ^ and using boost?  
Does these both refer to boost? Or is this below example of weight.  
{  
"query": {  
"multi\_match" : {  
"query": "London",  
"fields": ["City", " **AnotherCity^4**"]  
}

}
