We should add the metakg query support for searching on either of these fields by optionally expanding to include all descendant terms.\r\n\r\nWe can use [biolink-model-toolkit](https://github.com/biolink/biolink-model-toolkit) to get the descendant of a given term.\r\n\r\nIn metakg's query handler, we can add explicit `subject`, `object` and `predicate` query parameters, and an optional `expand` parameter when can take values of `subject`, `object` and `predicate` (include their combinations), so that we can expand either or multiple fields when needed. Default is still not expanding these terms.","author":{"url":"https://github.com/newgene","@type":"Person","name":"newgene"},"datePublished":"2023-03-07T06:35:00.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/185/smartAPI/issues/185"}
