[bogdanvlviv]

onoff - boolean type

I choose
must type.onoff #Can not add choose (true or false) to a boolean field
{
"query": {
"bool": {
"must": [
{
"match_all": {}
}
],
"must_not": [],
"should": []
}
},
"from": 0,
"size": 10,
"sort": [],
"facets": {}
}

need =>

{
"query": {
"bool": {
"must": [
{
"term": {
"onoff": # true or false
}
}
],
"must_not": [],
"should": []
}
},
"from": 0,
"size": 10,
"sort": [],
"facets": {}
}

I add 'term' ops for boolean type since that is the default operation for boolean type.
