| ------ | ------ |
| `author` | `IS` `IS NOT` |
| `milestone` | `IS` `IS NOT`|
| `label` | `IS` `IS NOT` |
| `my-reaction` | `IS` `IS NOT` |
| `weight`| `IS` `IS NOT` `GREATER THAN` `LESS THAN`|
| `subject` | `CONTAINS` `DOES NOT CONTAIN` |
| `description` | `CONTAINS` `DOES NOT CONTAIN` |
**Boolean Operators**:
`AND` `OR`
