Simple way to find which one are in the same company with me? - elasticsearch

Question

There is index have field like below, it saves who in which company and which position is
{
"createtime" : 1562844632272,
"post" : "director",
"personId" : 30007346088,
"comId" : 20010774891
}
now want to find the partners of someone, that is which person is in the same company. Now my implementation is
first find the person's related companies(at most 500)
{
"query": { "term": { "personId": 30007346088 } },
"sort": [ { "createtime": "desc" } ],
"_source": ["comId"],
"size":500
}
then find these companies' related persons and exclude the current person and remove duplicate partner(similarly at most 500 partners)
{
"query": {
"bool": {
"must": [{ "terms": { "comId": [20010774891,...] } } ],
"must_not": [ {"term":{"personId":30007346088}} ]
}
},
"aggs" : {
"personId" : {
"terms" : {
"field" : "personId",
"size": 500
}
}
},
"size":0
}
Obviously it's a little complicated, if could exist some more simple way to implement it?

Answer 1

It can work if data is stored in below format.
A unique document for each person , with document id same as person id and company stored as array
POST indexperson/_doc/1
{
"createtime": 1562844632272,
"personId": 1,
"company": [
{
"id": 100,
"post": "director"
},
{
"id": 100,
"post": "director"
}
]
}
Data:
[
{
"_index" : "indexperson",
"_type" : "_doc",
"_id" : "1",
"_score" : 1.0,
"_source" : {
"createtime" : 1562844632272,
"personId" : 1,
"company" : [
{
"id" : 100,
"post" : "director"
},
{
"id" : 101,
"post" : "director"
}
]
}
},
{
"_index" : "indexperson",
"_type" : "_doc",
"_id" : "2",
"_score" : 1.0,
"_source" : {
"createtime" : 1562844632272,
"personId" : 2,
"company" : [
{
"id" : 101,
"post" : "director"
}
]
}
},
{
"_index" : "indexperson",
"_type" : "_doc",
"_id" : "3",
"_score" : 1.0,
"_source" : {
"createtime" : 1562844632272,
"personId" : 3,
"company" : [
{
"id" : 100,
"post" : "director"
}
]
}
},
{
"_index" : "indexperson",
"_type" : "_doc",
"_id" : "4",
"_score" : 1.0,
"_source" : {
"createtime" : 1562844632272,
"personId" : 4,
"company" : [
{
"id" : 104,
"post" : "director"
}
]
}
}
]
Query:
Use (terms look up)[https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html]. Terms look up takes doc id as parameter
GET indexperson/_search
{
"query": {
"bool": {
"must": [
{
"terms": {
"company.id": {
"index": "indexperson",
"id": "1", --> get all docs in indexperson which match with company id
"path": "company.id"
}
}
}
],
"must_not": [
{
"term": {
"personId": {
"value": 2
}
}
}
]
}
}
}
Result:
"hits" : [
{
"_index" : "indexperson",
"_type" : "_doc",
"_id" : "1",
"_score" : 1.0,
"_source" : {
"createtime" : 1562844632272,
"personId" : 1,
"company" : [
{
"id" : 100,
"post" : "director"
},
{
"id" : 101,
"post" : "director"
}
]
}
},
{
"_index" : "indexperson",
"_type" : "_doc",
"_id" : "3",
"_score" : 1.0,
"_source" : {
"createtime" : 1562844632272,
"personId" : 3,
"company" : [
{
"id" : 100,

}
]
}
}
