elasticsearch - Elastic Search nested multimatch query -

-

so problem same described here, still remains unanswered on group.

my mapping:

{     "abstract": {         "properties": {             "summary": {                 "type": "string"             }         }     },     "authors": {         "type": "nested",         "properties": {             "first_name": {                 "type": "string"             },             "last_name": {                  "type": "string"             }         }     } }

and perform full-text search on both of these fields, unequally weighted. query comes mind, unfortunately doesn't work, this:

{     "query": {         "bool": {             "should": [{                 "multi_match": {                     "query": "higgs boson",                     "fields": ["abstract.summary^5", "author.last_name^2"]                 }             }]         }     } }

i don't results authors field, because of nested mapping. can't rid of nested property - use aggregations. elegant idea how solve it?

changing mapping following 1 uses include_in_root: true allow use query original wrote:

{     "abstract": {         "properties": {             "summary": {                 "type": "string"             }         }     },     "authors": {         "type": "nested",         "include_in_root": true,         "properties": {             "first_name": {                 "type": "string"             },             "last_name": {                  "type": "string"             }         }     } }

you may want index inner objects both nested fields , flattened object fields. can achieved setting include_in_parent true. - link

note: include_in_root may deprecated in future versions of elasticsearch in favor of copy_to.
