`^` is for [boosting](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#_boosting) while `~` in this case is for adjusting the [fuzziness](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#_fuzziness).

Hi @magnusbaeck,

{  
"query" : {  
"bool" : {  
"should" : [  
{  
"fuzzy" : {

"boost" : 100,  
"value" : "same old song and dance"  
}  
}  
},  
{  
"fuzzy" : {  
"title" : {  
"boost" : 50,  
"value" : "same",  
"fuzziness": 0.8  
}  
}  
},  
{  
"fuzzy" : {

"value" : "song",  
"fuzziness": 0.5  
}  
}
