To write a complex query in Django, you can use the `Q` objects for complex lookups and chaining filters. For example:

```python
from django.db.models import Q
from myapp.models import MyModel

# Example of a complex query
results = MyModel.objects.filter(
Q(field1__icontains='value1') | Q(field2__gte=10)
).exclude(field3='value2').order_by('-field4')
```

This query filters `MyModel` instances where `field1` contains 'value1' or `field2` is greater than or equal to 10, excludes those with `field3` equal to 'value2', and orders the results by `field4` in descending order.
