About empty values for a field. That'll teach me to try to remember without

i think the orriginal request was to find all docs where the field did
*not* have any value ... or in your vernacular: where Zip IS NULL

Ok, I'm confused again, not unusual To create a bitset for the following
condition
Zip IS NOT NULL
why invert the bitset?
a token containing the empty string matches documents that
contain that token
Isn't this exactly what he wants? Or am I mis-reading this? I'm reading it
as "any do

Try something like
TermDocs termDocs = reader.termDocs();
termDo
Try something like
TermDocs termDocs = reader.termDocs();
termDocs.seek(new Term("", ""));
while (termDocs.next()) {
bits.set(termDocs.doc());

Quoting the guys "it depends" ...
At root, a filter is a bitset. So size-wise, you are using 1 bit/doc (plus
some small overhead). Both the storage required and the time to construct
are dependent on the characteristics of your corpus. I guess the only way
you can answer that for your particular

You could use a filter. You'd just construct a filter with the bits on for
all docs that had that term. You could cache these to make future searchers
easier. I envision, say, caching one filter for each field and keeping them
around so you could re-use them whenever you wanted.
