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。两者在概念上做同样的事情。我几乎没有怀疑
1-这两者有什么区别? 2-哪一个更好用? 3-如果两者相同,为什么它们表现不同?
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查询能够搜索所需的文档
{
"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,它会搜索相同的记录,其中field2的值为401。
{
"query": {
"bool": {
"filter": [
{
"term": {
"called_party_address_number": "8701662243"
}
},
{
"term": {
"cause_code": "401"
}
}
]
}
}
}
UPDATE2:
通过将其包装在" constant_score" 中找到一个用bool / must查询来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"
}
}
]
}
}
}
}
}
记录我们正在尝试匹配" called_party_address_number":" 1235235757"和" cause_code":" 304"。
答案 0 :(得分:3)
第一个使用旧的1.x查询/过滤器语法(即filtered
个查询已被弃用,而不是bool/filter
)。
第二个使用新的2.x语法但不在过滤器上下文中(即您使用bool/must
而不是bool/filter
)。 2.x语法的查询等同于您的第一个查询(即在没有得分计算的过滤器上下文中运行=更快)将是这样的:
{
"query": {
"bool": {
"filter": [
{
"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
}
}
]
}
