creating an empty Filter() ?

Just for programming easiness,

f = F()

if condition:
   f = f & F(..)

Something like above is possible?

@apandita some people might prefer to always have a filter instead of conditional statements, imagine:

filter = None
if cat:
    filter = F('term', category=cat)
if type:
    if filter:
        filter &= F('term', type=type)
    else:
        filter = F('term', type=type)

with an empty filter you can do:

filter = F('match_all')
if cat:
    filter &= F('term', category=cat)
if type:
    filter &= F('term', type=type)

so it’s much more straightforward

Good idea - you can currently use F('match_all') that will behave exactly as you want (f == f & F('match_all'))

Do you (or anyone else) think that’s enough or we should make it a default for F()?

The same works for queries btw - Q('match_all')
