Short answer, no - it has zero sense.
But after some thinking, it can make some sense, potentially.
DisjunctionSumScorer holds child scorers semi-ordered in a binary heap.
Hypothetically inequality can be enforced at that heap, but heap might not
work anymore for such alignment. Hence, instead of
function queries to the rescue!
q={!func}def(query($a),query($b),query($c))
a=field1:value1
b=field2:value2
c=field3:value3
def or default function returns the value of the first argument that
matches. It's named default because it's more commonly used like
def(popularity,50) (return the value
Deepak,
I think your goal is to gain something in speed, but most likely the
function query will be slower than the query without score computation (the
filter query) - this stems from the fact how the query is executed, but I
may, of course, be wrong. Would you mind sharing measurements you
Sweet!

I understand that lucene's AND (), OR (||) and NOT (!) operators are
shorthands for REQUIRED, OPTIONAL and EXCLUDE respectively, which is why
one can't treat them as boolean operators (adhering to boolean algebra).
I have been trying to construct a simple OR expression, as follows
q =
