search - ElasticSearch - query documents: All given labels appear at least one time in a nested document -

-

consider few indexed documents (employees) containing nested documents (skills) 1 property, let's "label", each employee associated few skills. fetch employees (documents) elasticsearch index, master given set of skills, example "python" , "java".

i struggling find suitable query ensure all given skills ("python", "java") appear at least once in set of skills of employee, although do not have appear together!

my mapping similar one:

{   "mappings": {     "employee": {       "_all": { "enabled": false },       "properties": {         "id" : { "type": "integer" },         "first_name" : { "type": "string" },         "last_name" : { "type": "string" },          "skills": {           "type": "nested",           "properties": {             "label": { "type": "string" },             "rating": { "type": "integer" }           }         }        }     }   } }

so looking solutions (queries) on how retrieve desired results.

you need use two nested filters combined in bool/filter query, this:

post /employees/employee/_search {   "query": {     "bool": {       "filter": [         {           "nested": {             "path": "skills",             "query": {               "term": {                 "skills.label": "python"               }             }           }         },         {           "nested": {             "path": "skills",             "query": {               "term": {                 "skills.label": "java"               }             }           }         }       ]     }   } }
