Shlok Srivastava updated CALCITE-4233:
--------------------------------------
Description:
Currently, Calcite use constant_score API to build all the queries. which do
not boost the documents based on relevance score from any matching clause which
is supported by disMax API. It does not support dismax query builders -
[https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-dis-max-query.html.]
Dismax query -
{code:java}
GET /_search
{
"query": {
"dis_max": {
"queries": [
{
"bool": {
"should": [
{
"term": {
"Name": "James"
}
},
{
"term": {
"Name": "Peter"
}
},
{
"term": {
"Name": "Harry"
}
},
}
]
}
]
}
}{code}
Suggested solution - Queries with OR conditions should use disMax builders to
fetch the best matching documents.
Sample SQL query -
{code:java}
WHERE Name="James" OR Name="Peter" OR Name="Harry" {code}
Sample RelNode -
{code:java}
relB.or(relB.equals(relb.literal("Name"),relb.literal"James"),
relB.equals(relb.literal("Name"),relb.literal"Peter"),
relB.equals(relb.literal("Name"),relb.literal"Harry"){code}
