Elastic Search nested multimatch query

Question

So my problem is basically the same as described here, however it still remains unanswered on the group.

My mapping:

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

And I would like to perform a full-text search on both of these fields, probably unequally weighted. The query that comes to my mind, but unfortunately doesn't work, would be this:

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

I don't get any results from the authors field, because of its nested mapping. I also can't get rid of the nested property - I use it for aggregations. Any elegant idea how to solve it?

Answer 1

The only solution that I managed to work out, which is not handy nor elegant but somehow works is such query:

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

I'm also not sure if the boosting will work as expected, providing it's set in different queries. Any suggestions appreciated.
