Today, it doesn't seem that a $search index on a list of object documents allows for an embeddedDocument search to match on multiple properties within the document. So, if I have: [{ name: 'Doc 1', attached: [ { name: 'a', type: 'string' }, { name: 'b', type: 'number' }] }, { name: 'Doc 1', attached: [ { name: 'a', type: 'string' }, { name: 'b', type: 'string' }] }] I would like to be able to write a compound query like this: [ { $search: { index: "default", compound: { must: [ { embeddedDocument: { path: "attached", operator: { compound: { must: [ { text: { path: "attached.name", query: "b", }, }, { autocomplete: { path: "attached.type", query: "string", }, }, ], }, }, }, }, ], }, }, }] And for it to only find and return this: { name: 'Doc 1', attached: [ { name: 'a', type: 'string' }, { name: 'b', type: 'string' }] }
