# Operator Functions

Filter operator functions for constructing SpaceTrack query values. In Python, access these via `brahe.spacetrack.operators`:

```
from brahe.spacetrack import operators as op
op.greater_than("25544")  # ">25544"
```

## Comparison Operators

::: brahe._brahe.spacetrack_greater_than

::: brahe._brahe.spacetrack_less_than

::: brahe._brahe.spacetrack_not_equal

## Range and Pattern Operators

::: brahe._brahe.spacetrack_inclusive_range

::: brahe._brahe.spacetrack_like

::: brahe._brahe.spacetrack_startswith

## Time References

::: brahe._brahe.spacetrack_now

::: brahe._brahe.spacetrack_now_offset

## Special Values

::: brahe._brahe.spacetrack_null_val

::: brahe._brahe.spacetrack_or_list
