{ "index": { "_id": 4 }}
{ "price" : 30,"avaliable":false, "productID" : "QQPX-R-3956-#aD8" }

GET products/_mapping

对布尔值 查询，有算分

POST products/_search
{
"profile": "true",
"explain": true,
"query": {
"term": {
"avaliable": true
}
}
}

对布尔值，通过constant score 转成 filtering，没有算分

POST products/_search
{
"profile": "true",
"explain": true,
"query": {
"constant_score": {
"filter": {
"term": {
"avaliable": true
}
}
}
}
}
