# Filteration

In the Teamcare APIs, you can filter results using the `q` parameter, which is a special JSON object placed in the request body. For example, if the `Appointment` model includes a `date` attribute and filtering is supported, you can use keys like `date_#{specifier}` within `q`. Supported specifiers include `gt`, `lt`, `gteq`, and `lteq` for numeric or date fields, `in` for array fields and `cont` or `eq` for string fields.
