Allow 'wait_for' option for query param 'refresh' when using _reindex (as in the docs) #65031
Description
Elasticsearch version (bin/elasticsearch --version):
ES: 7.8.1
OS version (uname -a if on a Unix-like system):
Ubuntu 20.04 using docker for ES
Description of the problem including expected versus actual behavior:
Seems that when trying to _reindex from one index to another (same cluster) the option 'wait_for' for refresh query param is not allowed (as in the docs is saying "If true, Elasticsearch refreshes the affected shards to make this operation visible to search, if wait_for then wait for a refresh to make this operation visible to search, if false do nothing with refreshes. Valid values: true, false, wait_for. Default: false.")
Steps to reproduce:
POST _reindex?refresh=wait_for
{
"source": {
"index": "old_index",
},
"dest": {
"index": "new_index"
}
}
And the error it throws:
{
"error" : {
"root_cause" : [
{
"type" : "illegal_argument_exception",
"reason" : "Failed to parse value [wait_for] as only [true] or [false] are allowed."
}
],
"type" : "illegal_argument_exception",
"reason" : "Failed to parse value [wait_for] as only [true] or [false] are allowed."
},
"status" : 400
}
