Comment:
You should be able to use the
[https://docs.djangoproject.com/en/1.9/ref/models/database-
functions/#concat Concat] functions for this purpose:
{{{
from django.db.models import Value
from django.db.models.functions import Concat
User.objects.annotate(
name=Concat('first_name', Value(' '), 'last_name'),
).filter(name__icontains=value)
}}}
Or simply using `Q` objects:
{{{#!python
from django.db.models import Q
User.objects.annotate.filter(
Q(first_name__icontains=value) | Q(last_name__icontains=value),
)
}}}
