A search with standard settings ranks hits in documents with fewer words higher than longer texts. The word count seems to also take all nested documents into consideration.
Lets say I have:
PUT /books/_doc/1
{
"editions": [
{
"title": "apes"
}
]
}
PUT /books/_doc/2
{
"editions": [
{
"title": "a group of apes"
}
]
}
PUT /books/_doc/3
{
"editions": [
{
"title": "chimpansee kingdom"
},
{
"title": "apes"
}
]
}
Search:
POST /books/_search
{
"query": {
"bool": {
"should": [
{
"nested": {
"path": "editions",
"query": {
"match": {
"editions.title": {
"query": "apes"
}
}
}
}
}
]
}
}
}
Right now book id 1 ranks highest followed by 2 and last comes 3.
Can I restrict that effect to the length of the nested document with the hit instead of taking all nested documents into account so that book id 1 and 3 rank hightest (equally) followed by 2?
