**Feature summary** (what you would like to be able to do and where):
I would like to use MediaWiki's API to search for schemas in a Wikibase, just as it is possible to search for entities, properties, etc. through //wbsearchentities//. As far as I can tell, the API docs do not mention any operation similar to the one proposed.
**Use case(s)** (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
I'm participating in the development of [[ https://wikishape.weso.es/ | WikiShape ]] and one of the tools allows users to analyze Wikidata schemas. We would like to suggest schemas as you type in their names (like we do with entities [[ https://wikishape.weso.es/item | here ]]), however this is not possible without tricks because there is no way to search for schemas by label.
Maybe a new value "schema" could be added to the //type// parameter in //wbsearchentities//.
**Benefits** (why should this be implemented?):
Working programmatically with Wikidata or any other Wikibase instance in general would be way easier and better tools could be created.
