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 theyre returned. They let you select only the resources that match certain criteriasuch 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). Using filters reduces payload size and improves performance by avoiding clientside postprocessing. Support for specific operators varies by resource and property (not all fields are filterable), and some advanced scenarioslike filtering on certain directory properties or using $count with filtersrequire the ConsistencyLevel: eventual header.
