# FilterRule

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

## Fields
- `field` (string): (nullable)
- `operator` ([DataFilterOperator](https://devportal.demo.winkpg.io/docs/api/models/DataFilterOperator.md)): Defines the set of supported operators used to build filter expressions for querying data.
  Values:
  - `Equals`
  - `NotEquals`
  - `Contains`
  - `StartsWith`
  - `EndsWith`
  - `GreaterThan`
  - `GreaterThanOrEqual`
  - `LessThan`
  - `LessThanOrEqual`
  - `IsNull`
  - `IsNotNull`
- `value` (object): The value the rule compares against, coerced to the target column's type when the predicate is  built. Declared `object?` so one rule shape serves every column type. (nullable)
- `caseInsensitive` (boolean): When true, string comparison operators (Equals, StartsWith, Contains, EndsWith)  compare case-insensitively. String comparisons are case-sensitive by default.
