Microsoft Graph Filter Operators

Microsoft Graph filter operators are the OData $filter expressions you add to Graph API requests to narrow results on the server before they’re returned. They let you select only the resources that match certain criteria—such as equality and comparison checks (eq, ne, gt, ge, lt, le), logical combinations (and, or, not), string matching (startswith, endswith, contains), membership tests (in), and collection predicates (any, all).
