elasticsearch run multiple different query in one call - angularjs

Question

I want to run 3 differents query (on the same index) with one call on elasticsearch service.
Is this possible ?
More elaborate question :
I make an autocomplete function in angularjs who search on 3 fields and display them :
"T_FAMILY" + "T_GENUS" + "T_SCIENTIFICNAME".
i was making only one query :
"query" : { "query_string" : { "query" : "T_FAMILY:" +value +" or T_GENUS:"+value+ " or T_SCIENTIFICNAME:"+value} }
// value is the user input and can contain wildcard *
but not revelant results.
Now i want to make 3 different query and sort each one by score. and finally get the 3 results and
merge them in an array and sort by score (i do this by my addKeyword() function).
var keywords = [];
keywords.push(val);
$scope.isHide.logo=true;
return elasticQuery.search({
index: $scope.domaine,
size: 20,
_source: false,
body: {
"fields" : ["T_FAMILY","T_GENUS","T_SCIENTIFICNAME"],
"query": { "bool" : {"must" : [{"wildcard" : { "T_FAMILY" : val }}]}},
"sort" : { "_score" : "desc" }
}
}).then(function (response){
addKeyword(response,keywords);
return elasticQuery.search({
index: $scope.domaine,
size: 20,
_source: false,
body: {
"fields" : ["T_FAMILY","T_GENUS","T_SCIENTIFICNAME"],
"query": {"bool" : {"must" : [{"wildcard" : { "T_GENUS" : val }}]}},
"sort" : { "_score" : "desc" }
}
}).then(function (response) {
addKeyword(response,keywords);
return elasticQuery.search({
index: $scope.domaine,
size: 20,
_source: false,
body: {
"fields" : ["T_FAMILY","T_GENUS","T_SCIENTIFICNAME"],
"query": {"bool" : {"must" : [{"wildcard" : { "T_SCIENTIFICNAME" : val }}]}},
"sort" : { "_score" : "desc" }
}
}).then(function (response) {
addKeyword(response,keywords);
return keywords;
});
return keywords;
});
});
I didn't find anything who help so i make 3 imbricated call of elastichsearch in my js code but it's not the best way maybe.
Thanks

it is possible to run differents queries in elasticsearch with "dis_max" :
return elasticQuery.search({
index: $scope.domaine,
size: 20,
_source: false,
body: {
//"min_score" : 0.50,
"fields" : ["T_FAMILY","T_GENUS","T_SCIENTIFICNAME"],
"highlight": {"pre_tags": ["<strong>"], "post_tags": ["</strong>"], "fields": { "T_FAMILY": {},"T_GENUS" : {}, "T_SCIENTIFICNAME": {} }},
"query" : {
"dis_max" : {
"tie_breaker" : 0.0,
"boost" : 1.0,
"queries" : [
{"wildcard" : { "T_FAMILY" : val }},
{"wildcard" : { "T_GENUS" : val }},
{"wildcard" : { "T_SCIENTIFICNAME" : val }}
]
}
},
"sort" : { "_score" : "desc" }
}
}).then(function (response){
return addKeywords(response,keywords);
});
