## Use filter with collections Use `?filter=` parameter on collections to retrieve a subset of the collection based on the provided filter. Fields and values in the filter are separated with `:`. Query structure: - To use exact match, use `:`: ``` ?filter=firstName:John ``` - To use substring match, use `~`: ``` ?filter=firstName~Jo ``` - To use multiple values, use `,` as a separator of values: ``` ?filter=firstName:John,Bob ?filter=status:success,pending ``` - To use range filter, use `..`: ``` ?filter=amount:1..10 ?filter=birthDate:1900-01-01T00:00:00.000Z..2000-01-01T00:00:00.000Z ``` - To negate the result of the filter, use `-`: ``` ?filter=-firstName:John ``` - To use logical AND, use either `AND` operator (case-insensitive) or an empty string: ``` ?filter=firstName:John AND isAdmin:true ``` - To use logical OR, use `OR` operator: ``` ?filter=firstName:John OR lastName:Doe ``` - Datetime-based fields accept values formatted in the `ISO 8601` format: ``` ?filter=createdTime:2021-02-14T13:30:000Z ``` - If you want to search for a value that contains a space, `,` or `..` operators, you need to wrap the value in quotes. You can escape quotes inside of quotes with a backslash `\`. Both single and double quotes are supported: ``` ?filter=description:"The story called \"The Sky and the Sea.\"" ``` - You do not need to wrap a `number`, `boolean` or `null` into quotes: ``` ?filter=age:18 ?filter=isAdmin:true ?filter=description:null ```
