我试图了解它们之间的区别:
以下是条款查询:
GET _search
{
"query": {
"terms": {
"childcareTypes": [
"SOLE_CHARGE",
"OUT_OF_SCHOOL",
"BABY_SITTING"
],
"minimum_match": 3
}
}
}
以下是已过滤版本:
GET _search
{
"query": {
"filtered": {
"filter": {
"terms": {
"childcareTypes": [
"SOLE_CHARGE",
"OUT_OF_SCHOOL",
"BABY_SITTING"
],
"execution": "and"
}
}
}
}
}
两者的总命中数为8000(与我的指数相比)。
以下是“普通”字词查询的结果:
{
"took": 7,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 8000,
"max_score": 5.134171,
"hits": [
{
"_index": "bignibou",
"_type": "advertisement",
"_id": "AUs2T2lt3L5LNr7nkot2",
"_score": 5.134171,
"_source": {
"childcareWorkerType": "AUXILIAIRE_PARENTALE",
"childcareTypes": [
"SOLE_CHARGE",
"OUT_OF_SCHOOL",
"BABY_SITTING"
],
"address": {
"latitude": 48.8532558,
"longitude": 2.36584
},
"giveBath": "EMPTY"
}
},
...
以下是“已过滤”查询的结果:
{
"took": 3,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {

"address": {

},
....
那么两者之间有什么区别?
答案 0 :(得分:2)
这与查询和过滤器(more information here)之间的差异有关。
在您的情况下,与terms
查询不同,terms
过滤器:
_score
1(查看结果)因此,最大的区别是filtered
查询会比普通的查询更快。 terms
查询。
