I seem to have the same problem with manufactureYear as with enginePower: I cannot create a query like “manufactureYear >= YYYY and manufactureYear <= YYYY”.
Although manufactureYear is of type “string or number” according to the documentation i get the following error when creating a query like { manufactureYear: { _gt: 2018} }:
{status: 400, code: ‘QUERY_VALIDATION_FAILED’, title: ‘Query validation failed’, detail: ‘Failed to validate query: Value “2018” can not be used for property “manufactureYear” of type “string”’}
I assume I will get another error if I give the year as a string instead of a number (but I haven’t tested that yet).
Should I create another ticket for this issue?
