【问题描述】:
我在 ES 中有两个查询。两者在同一组文档上的周转时间不同。两者在概念上都在做同样的事情。我没有什么疑问
1- 这两者有什么区别? 2-哪个更好用? 3- 如果两者相同,为什么它们的表现不同?
1. Filtered bool
{
"from": 0,
"size": 5,
"query": {
"filtered": {
"filter": {
"bool": {
"must": [
{
"term": {
"called_party_address_number": "1987112602"
}
},
{
"term": {
"original_sender_address_number": "6870340319"
}
},
{
"range": {
"x_event_timestamp": {
"gte": "2016-07-01T00:00:00.000Z",
"lte": "2016-07-30T00:00:00.000Z"
}
}
}
]
}
}
}
},
"sort": [
{
"x_event_timestamp": {
"order": "desc",
"ignore_unmapped": true
}
}
]
}
2. Simple Bool
{
"query": {
"bool": {
"must": [
{
"term": {
"called_party_address_number": "1277478699"
}
},
{
"term": {
"original_sender_address_number": "8020564722"
}
},
{
"term": {
"cause_code": "573"
}
},
{
"range": {
"x_event_timestamp": {
"gt": "2016-07-13T13:51:03.749Z",
"lt": "2016-07-16T13:51:03.749Z"
}
}
}
]
}
},
"from": 0,
"size": 10,
"sort": [
{
"x_event_timestamp": {
"order": "desc",
"ignore_unmapped": true
}
}
]
}
映射:
{
"ccp": {
"mappings": {
"type1": {
"properties": {
"original_sender_address_number": {
"type": "string"
},
"called_party_address_number": {
"type": "string"
},
"cause_code": {
"type": "string"
},
"x_event_timestamp": {
"type": "date",
"format": "strict_date_optional_time||epoch_millis"
},
.
.
.
}
}
}
}
}
更新 1:
我在同一组数据上尝试了 bool/must 查询和 bool/filter 查询,但我发现了奇怪的行为
1- bool/must query 是否能够搜索到想要的文档
{
"query": {
"bool": {
"must": [
{
"term": {
"called_party_address_number": "8701662243"
}
},
{
"term": {
"cause_code": "401"
}
}
]
}
}
}
2- 虽然 bool/filter 无法搜索文档。如果我删除第二个字段条件,它会搜索字段 2 值为 401 的同一记录。
{
"query": {
"bool": {
"filter": [
{
"term": {
"called_party_address_number": "8701662243"
}
},
{
"term": {
"cause_code": "401"
}
}
]
}
}
}
更新2:
通过将其包装在 "constant_score" 中,找到了使用 bool/must 查询抑制评分阶段的解决方案。
{
"query": {
"constant_score": {
"filter": {
"bool": {
"must": [
{
"term": {
"called_party_address_number": "1235235757"
}
},
{
"term": {
"cause_code": "304"
}
}
]
}
}
}
}
}
我们尝试匹配的记录有“called_party_address_number”:“1235235757”和“cause_code”:“304”。
