[英]Highlight nested object in Elasticsearch
Here is my sample dataset,这是我的示例数据集,
{
"parent":[
{
"name":"John Doe 1",
"age":"100 year",
"sex":"male",
"child":[
{
"name":"Jane Doe 1",
"height":100.00,
"width":100.00
},
{
"name":"Jane Doe 2",
"height":100.00,
"width":100.00
}
]
},
{
"name":"John Doe 2",
"age":"100 year",
"sex":"male",
"child":[
{
"name":"Jane Doe 3",
"height":100.00,
"width":100.00
},
{
"name":"Jane Doe 4",
"height":100.00,
"width":100.00
}
]
}
]
}
And my definition:而我的定义:
{
"settings": {
"index": {
"analysis": {
"analyzer": {
"default": {
"type": "simple"
}
}
}
}
},
"mappings": {
"_doc": {
"properties": {
"parent": {
"type": "nested",
"properties": {
"name": {
"type": "keyword"
},
"age": {
"type": "text"
},
"sex": {
"type": "text"
},
"child": {
"type": "nested",
"properties": {
"name": {
"type": "text"
},
"height": {
"type": "float"
},
"width": {
"type": "float"
}
}
}
}
}
}
}
}
}
I'm using the following query to look for matches in the parent.name
property and can get highlights.我正在使用以下查询在parent.name
属性中查找匹配项,并且可以获得高亮显示。
{
"query": {
"bool": {
"should": [
{
"nested": {
"inner_hits": {
"highlight": {
"fields": {
"parent.name": {}
},
"number_of_fragments": 0,
"pre_tags": [
"<span>"
],
"post_tags": [
"</span>"
]
}
},
"path": "parent",
"query": {
"bool": {
"must": [
{
"match": {
"parent.name": {
"query": "John",
"fuzziness": "AUTO:3,6",
"prefix_length": "0"
}
}
}
]
}
}
}
}
],
}
},
"_source": ["parent"],
"sort": [
{
"_score": {
"order": "desc"
}
},
{
"createdOn": {
"order": "desc"
}
}
]
}
Is there a way to get inline highlights for the matches in the child.name
properties also so that it would be easy to find exactly which element of that corresponding array got matched?有没有办法获得child.name
属性中匹配项的内联突出显示,以便很容易找到匹配的相应数组的哪个元素?
For example, for the given sample data, if I search by "Doe", I'm expecting to get 6 hits, whereas if I search by "Jane", I would get only 4.例如,对于给定的样本数据,如果我按“Doe”搜索,我预计会得到 6 次点击,而如果我按“Jane”搜索,我只会得到 4 次。
You can simply add another nested query
clause inside you top level should
.您可以简单地在顶级should
添加另一个nested query
子句。
Here's how your query should look:您的查询应如下所示:
{
"query": {
"bool": {
"should": [
{
"nested": {
"inner_hits": {
"highlight": {
"fields": {
"parent.name": {}
},
"number_of_fragments": 0,
"pre_tags": [
"<span>"
],
"post_tags": [
"</span>"
]
}
},
"path": "parent",
"query": {
"bool": {
"must": [
{
"match": {
"parent.name": {
"query": "John Doe 1"
}
}
}
]
}
}
}
},
{
"nested": {
"inner_hits": {
"highlight": {
"fields": {
"parent.child.name": {}
},
"number_of_fragments": 0,
"pre_tags": [
"<span>"
],
"post_tags": [
"</span>"
]
}
},
"path": "parent.child",
"query": {
"bool": {
"must": [
{
"match": {
"parent.child.name": {
"query": "Jane Doe 1"
}
}
}
]
}
}
}
}
],
"minimum_should_match": 1
}
},
"_source": ["parent"],
"sort": [
{
"_score": {
"order": "desc"
}
},
{
"createdOn": {
"order": "desc"
}
}
]
}
