### Summary When searching for a conan package using `conan search` searching for a full package recipe results in a `404 Not Found` error. ### Steps to reproduce 1. Create a conan package and upload it to the GitLab remote. 1. Search for the package only using the package name, not the full recipe and verify it successfully returns the package name 1. Search for the package by full recipe and a 404 error is received. ### Example Project https://gitlab.com/sabrams/my-package-registry/-/packages/59602 ### What is the current *bug* behavior? A 404 error is returned when searching for a full recipe ### What is the expected *correct* behavior? A successful response should be returned. ### Relevant logs and/or screenshots ```sh conan search Hello/0.1@sabrams+my-package-registry/beta -r=gitlab DEBUG :conan_api.py [163]: INIT: Using config '.....conan.conf' [2020-02-27 10:52:40,050] DEBUG :tracer.py [155]: CONAN_API: search_packages(query=None,remote_name=gitlab,outdated=False) [2020-02-27 10:52:40,052] DEBUG :rest_client_common.py[160]: REST: ping: https://gitlab.com/api/v4/packages/conan/v1/ping [2020-02-27 10:52:40,056] DEBUG :rest_client.py [38]: REST: Cached capabilities for the remote: [] [2020-02-27 10:52:41,406] DEBUG :rest_client_common.py[185]: REST: get: https://gitlab.com/api/v4/packages/conan/v1/conans/Hello/0.1/sabrams+my-package-registry/beta/search [2020-02-27 10:52:41,406] DEBUG :rest_client_common.py[36]: REST ERROR: <class 'conans.errors.NotFoundException'> [2020-02-27 10:52:41,484] ERROR: {"error":"404 Not Found"}. [Remote: gitlab] ``` ### Output of checks This bug happens on GitLab.com ### Possible fixes The name only search hits this api endpoint: ```sh GET https://gitlab.com/api/v4/packages/conan/v1/conans/search?q=Hello ``` The full recipe search hits a different endpoint: ```sh GET https://gitlab.com/api/v4/packages/conan/v1/conans/Hello/0.1/sabrams+my-package-registry/beta/search ``` This endpoint is not implemented in the [conan package code](https://gitlab.com/gitlab-org/gitlab/blob/master/ee/lib/api/conan_packages.rb#L46). To respond to these search requests, the endpoint will need to be added following the [conan code](https://github.com/conan-io/conan/blob/develop/conans/model/rest_routes.py#L120) This also returns a [different response format](https://github.com/conan-io/conan/blob/develop/conans/server/service/common/search.py#L48) from the existing search so additional logic will be needed as well. <!-- triage-serverless v3 PLEASE DO NOT REMOVE THIS SECTION --> *This page may contain information related to upcoming products, features and functionality.
