Match all queryedit
The most simple query, which matches all documents, giving them all a _score
of 1.0.
GET /_search
{
"query": {
"match_all": {}
}
}
The _score can be changed with the boost parameter:
GET /_search
{
"query": {
"match_all": { "boost" : 1.2 }
}
}
Match None Queryedit
This is the inverse of the match_all query, which matches no documents.
GET /_search
{
"query": {
"match_none": {}
}
}
