REST query: $filter by AllProperties of _api/web/webs

Question

Is there any way to query subsites via REST and include $filter for properties in SPWeb's property bag, like this:

http://site.company.com/workspaces/_api/web/webs?$expand=AllProperties&$select=Title,ServerRelativeUrl,AllProperties/WorkspaceType&$filter=(AllProperties/WorkspaceType eq 'IT')

So I've created SPWeb, added WorkspaceType property with value IT in the AllProperties of the SPWeb, and would like to list all SPWebs under the /workspaces site that have a specific value in the WorkspaceType property.

Omitting the $filter does return the subwebs fine, including that specific property.

Answer 1

I think you'll find that filtering by specific properties in the property bag is not possible. I can think of two possible ways to work around that limitation:

1. Do the filtering in code after fetching all the subwebs.
2. Use Search and Indexed Properties instead of the Webs API endpoint
