The boosting query can be used to effectively demote results that match a given query. Unlike the “NOT” clause in bool query, this still selects documents that contain undesirable terms, but reduces their overall score.
{
"boosting" : {
"positive" : {
"term" : {
"field1" : "value1"
}
},
"negative" : {
"term" : {
"field2" : "value2"
}
},
"negative_boost" : 0.2
}
}
