I have severals doc and each doc contains nested fields and I want to order by position depending on thematic id
Document1 :
{
...
"thematics":[
{
"id": 1,
"position": 100
},
{
"id": 2,
"position": 1
}
]
}
Document2:
{
...
"thematics":[
{
"id": 2,
"position": 3
}
]
}
Document3:
{
...
"thematics":[
{
"id": 1,
"position": 40
}
]
}
For example, I would like to get only documents with thematics which contains id = 2 So I did something like that
$filter = BoolQuery();
...
$filter->addMust(new Query\Term(["thematics.id" => 2]));
And then when I want to apply sort method on position where thematic id = 2 and not something else.
I tried something like that :
case 'atp': // asc thematic position
$sort = [
"_score",
[
"thematics.position" => [
"order" => "asc",
"missing" => 0,
],
],
];
break;
...
$this->setSort($sort); // call parent method setSort(array()) of elastica-ruflin
Response example :
First case expected : If I want to display all documents from thematic 1 the order must be : Document3 then Document1.
Second case expected : If I want to display all documents from thematic 2 the order must be : Document1 then Document2.
But for now what I've got is :
- First case : Document3, Document1
- Second case : Document2, Document1
I'm guessing that it takes the first thematic's position of document1 to sort in both cases.
Edit : I tried to change de mapping with a nested type
thematics:
type: nested
properties:
label: { type: string, index: not_analyzed }
slug: { index: not_analyzed }
name: { type: string, index: not_analyzed }
position: { type: integer }
id: { type: integer }
And the query but still not working
{
"query": {
"function_score": {
"query": {
"bool": {
"must": [
{
"bool": {
"must": [
{
"match_all": {}
}
]
}
}
],
"filter": [
{
"bool": {
"must": [
{
"term": {
"is_searchable": true
}
},
{
"nested": {
"path": "thematics",
"query": {
"term": {
"thematics.id": {
"value": 2
}
}
}
}
},
{
"exists": {
"field": "valuation"
}
},
{
"bool": {
"should": [
{
"bool": {
"must": [
{
"exists": {
"field": "valuation.translations.fr.title"
}
}
]
}
},
{
"bool": {
"must": [
{
"exists": {
"field": "valuation.translations.en.title"
}
}
]
}
},
{
"bool": {
"must": [
{
"term": {
"commercial_subcategory.category.id": 33
}
}
]
}
}
]
}
}
]
}
}
]
}
},
"boost_mode": "multiply",
"functions": [
{
"field_value_factor": {
"field": "booster",
"modifier": "square"
}
}
]
}
},
"sort": [
"_score",
{
"thematics.position": {
"order": "asc",
"missing": 0,
"mode": "min",
"nested_filter": {
"term": {
"thematics.id": {
"value": 2
}
}
}
}
}
]
}
Edit2: I get around the problem. I changed my mapping so each document looks like that :
{
...
"thematics":[
"1": {
"id": 1,
"position": 100
},
"2": {
"id": 2,
"position": 1
}
]
}
And then I apply a Bool Query must / Exists Filter on "thematics.".$thematicId
And finally, my sort method looks like this :
case 'atp': // asc thematic position
$sort = [
"_score",
[
"thematics." . $thematicId . ".position" => [
"order" => "asc",
"missing" => 0,
],
],
];
break;
...
$this->setSort($sort); // call parent method setSort(array()) of elastica-ruflin
