The search service takes a `from` offset next to the page size and applies it after the cross-space merge; every space answers the full prefix up to from+size, since an offset cannot be distributed. Pages are stable: both engines and the merge break score ties by id, and OpenSearch counts every match (track_total_hits). No engine pages beyond the first 10000 matches, the OpenSearch result window, so a from and size reaching beyond it are rejected on both engines. `page_size` becomes optional on the wire: absent is the default of 200, 0 asks for no matches, -1 for all; WebDAV and the tags listing set it accordingly, and the WebDAV report's `<oc:offset>`, parsed since the report exists and never read, now pages the merged list. The gRPC wrapper passes the request through and keys its cache by the whole request.
Webdav
The webdav service, like the frontend service, provides a HTTP API following the webdav protocol. It receives HTTP calls from requestors like clients and issues gRPC calls to other services executing these requests. After the called service has finished the request, the webdav service will render their responses in xml and sends them back to the requestor.
Endpoints Overview
Currently, the webdav service handles request for two functionalities, which are Thumbnails and Search.
Thumbnails
The webdav service provides various GET endpoints to get the thumbnails of a file in authenticated and unauthenticated contexts. It also provides thumbnails for spaces on different endpoints.
See the thumbnail service for more information about thumbnails.
Search
The webdav service provides access to the search functionality. It offers multiple REPORT endpoints for getting search results.
See the search service for more details about search functionality.
Scalability
The webdav service does not persist any data and does not cache any information. Therefore multiple instances of this service can be spawned in a bigger deployment like when using container orchestration with Kubernetes, without any extra configuration.
