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?
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.
