[BUG] Asynchronous searching does not work with wildcard indexes. (double escape) #319
Description
What is the bug?
Calling asynchronous_search.search and passing an index that has a wildcard (ie. index: "test-*") results in the error index_not_found_exception with reason: no such index [test-%2A]
How can one reproduce the bug?
@client.indices.create(index: "test-one")
@client.indices.create(index: "test-two")
@client.asynchronous_search.search(index: "test-*")
A full request/response cycle:
> @client.indices.create(index: "test-one")
-- PUT https://admin:***********@opensearch:9200/test-one [status:200, request:0.111s, query:n/a]
-- < {"acknowledged":true,"shards_acknowledged":true,"index":"test-one"}
=> {"acknowledged" => true, "shards_acknowledged" => true, "index" => "test-one"}
> @client.indices.create(index: "test-two")
-- PUT https://admin:***********@opensearch:9200/test-two [status:200, request:0.039s, query:n/a]
-- < {"acknowledged":true,"shards_acknowledged":true,"index":"test-two"}
=> {"acknowledged" => true, "shards_acknowledged" => true, "index" => "test-two"}
> @client.asynchronous_search.search(index: "test-*")
-- POST https://admin:***********@opensearch:9200/_plugins/_asynchronous_search?index=test-%252A [status:200, request:0.004s, query:n/a]
-- < {"id":"FlJJQjA4cUpzU0Yycl9PVUVDUEZIX2cGODQxMTk5FERCdmNiNW9CeVhFWkxsWm80aldOBDMzNjM=","state":"CLOSED","start_time_in_millis":1762813338253,"expiration_time_in_millis":1762899738253,"error":{"type":"index_not_found_exception","reason":"no such index [test-%2A]","index":"test-%2A","resource.id":"test-%2A","resource.type":"index_or_alias","index_uuid":"_na_"}}
=>
{"id" => "FlJJQjA4cUpzU0Yycl9PVUVDUEZIX2cGODQxMTk5FERCdmNiNW9CeVhFWkxsWm80aldOBDMzNjM=",
"state" => "CLOSED",
"start_time_in_millis" => 1762813338253,
"expiration_time_in_millis" => 1762899738253,
"error" => {"type" => "index_not_found_exception", "reason" => "no such index [test-%2A]",
"index" => "test-%2A", "resource.id" => "test-%2A", "resource.type" => "index_or_alias",
"index_uuid" => "_na_"}}
What is the expected behavior?
I would expect the search to succeed and search all indices matching test-*.
What is your host/environment?
Alpine Linux
Linux api 6.10.14-linuxkit #1 SMP Tue Oct 14 07:32:13 UTC 2025 aarch64 Linux
Do you have any additional context?
The problem is that the query parameters are being escaped twice. Once in the async-search code and once in the underlying transport.

https://github.com/opensearch-project/opensearch-ruby/blob/main/lib/opensearch/transport/transport/connections/connection.rb#L79
As far as I can tell, async-search is the only endpoint that passes the index on the query string. All of the others either pass it in the body or build it into the URL itself.
