对特定字段的数据进行排序在弹性中首先给出不相关的数据
I want to search data in elastic search version 5.2.1 such that the exact match term should come first and then all the relevant matches i.e fuzzy data.
The data needs to be sorted on the basis of relevancy (relevancy includes the creation date of item and then item inventory)
The query that i am trying is :
GET dummy/_search
{
"track_scores": true,
"from" : 0,
"size" : 24,
"query" : {
"bool" : {
"must" : [
{
"bool" : {
"should" : [
{
"match" : {
"itemNameWeb" : {
"query" : "swetashirt",
"operator" : "OR",
"analyzer" : "standard",
"prefix_length" : 0,
"max_expansions" : 50,
"minimum_should_match" : "66%",
"fuzzy_transpositions" : false,
"lenient" : false,
"zero_terms_query" : "NONE",
"boost" : 1.0
}
}
},
{
"match" : {
"itemNameWeb" : {
"query" : "swetashirt",
"operator" : "OR",
"analyzer" : "standard",
"fuzziness" : "1",
"prefix_length" : 0,
"max_expansions" : 50,
"minimum_should_match" : "66%",
"fuzzy_transpositions" : true,
"lenient" : false,
"zero_terms_query" : "NONE",
"boost" : 1.0
}
}
}
],
"disable_coord" : false,
"adjust_pure_negative" : true,
"boost" : 1.0
}
}
],
"disable_coord" : false,
"adjust_pure_negative" : true,
"boost" : 1.0
}
},
"sort" : [
{
"createDate" : {
"order" : "desc"
}
},
{
"itemTotalInventory" : {
"order" : "desc"
}
}
]
}
上面的查询没有给出预期的结果，因为排序导致的精确匹配会因为排序而下降
到目前为止尝试的解决方案与建议的解决方案添加了恒定分数：
GET dummy/_search

"from": 0,
"size": 1000,
"query": {
"bool": {
"must": [

Fidato T 恤结果应该是第一位的，但它给出了 2 件装男士印花全袖 T 恤-M 作为最高结果。

The query above is not giving expected result as the exact matches due to sorting goes down because of sorting
The solution tried so far from the proposed solution adding constant score:
GET dummy/_search
{
"track_scores": true,
"from": 0,
"size": 1000,
"query": {
"bool": {
"must": [
{
"bool": {
"should": [
{
"constant_score": {
"filter": {
"bool": {
"should":{
"match": {
"itemNameWeb": {
"query": "fidato tshirt",
"operator": "OR",
"analyzer": "standard",
"prefix_length": 0,
"max_expansions": 50,
"minimum_should_match": "66%",
"fuzzy_transpositions": false,
"lenient": false,
"zero_terms_query": "NONE",
"boost": 1
}
}
}
}
},
"boost": 2
}
},
{
"constant_score": {
"filter": {
"bool": {
"should":{
"match": {
"itemNameWeb": {
"query": "fidato tshirt",
"operator": "OR",
"analyzer": "standard",
"fuzziness": "1",
"prefix_length": 0,
"max_expansions": 50,
"minimum_should_match": "66%",
"fuzzy_transpositions": true,
"lenient": false,
"zero_terms_query": "NONE",
"boost": 1
}
}
}
}
},
"boost": 1
}
}
],
"disable_coord": false,
"adjust_pure_negative": true,
"boost": 1
}
}
],
"disable_coord": false,
"adjust_pure_negative": true,
"boost": 1
}
},
"sort": [
"_score",
{
"createDate.keyword": {
"order": "desc"
}
},
{
"itemTotalInventory": {
"order": "desc"
}
}
]
}
The sample output result from the above GET query
{
"took": 2,
"timed_out": false,
"_shards": {

},
"sort": [

Fidato T-Shirt result should have come first but its giving Pack of 2 Men's Printed Full Sleeves Tshirt-M as top most result .

如果您通过
constant_score查询包装每个匹配查询，并给出精确匹配的boost值，该值高于模糊的 boost 值，那么如果您之前按_score排序您的排序标准，您就可以实现这一点。以下查询应该适合您：If you wrap each match query by a
constant_scorequery and give exact match'sboostvalue higher than the fuzzy's boost value then if you sort by_scorebefore your sorting criteria, you can achieve this. Following query should work for you:
