[BUG] Version conflict during document recreation

[singh-abhishek]

Describe the bug

If I create a document with version=1 and version_type=external_gte and then delete the document, the subsequent document creation with version=1 and version_type=external_gte fails with version conflict.

To Reproduce

#create index
curl -XPUT "http://opensearch.opensearch:9200/identifier" -H 'Content-Type: application/json' -d'{ "settings": { "index": { "number_of_shards": 1, "number_of_replicas": 1 } }, "mappings": { "properties": { "id": { "type": "integer" } } }}'

#insert document
curl -XPUT "http://opensearch.opensearch:9200/identifier/_doc/1?version=1&version_type=external_gte" -H 'Content-Type: application/json' -d'{ "id": 1}'

#delete document
curl -XDELETE "http://opensearch.opensearch:9200/identifier/_doc/1"

#insert same document again
curl -XPUT "http://opensearch.opensearch:9200/identifier/_doc/1?version=1&version_type=external_gte" -H 'Content-Type: application/json' -d'{ "id": 1}'

#get this error
{
"error" : {
"root_cause" : [
{
"type" : "version_conflict_engine_exception",
"reason" : "[1]: version conflict, current version [2] is higher than the one provided [1]",
"index" : "identifier",

],

"index" : "identifier",
"shard" : "0",
"index_uuid" : "45deXZY1RqWBO5cj8v0c7A"
},
"status" : 409
}

Expected behavior

A document with the same version and content should be recreated after it has been already deleted.
