reduced to:

OR (-visibleto:[ * TO *] AND visiblefrom:[0 TO <now in ms>])
OR ( visiblefrom:[0 TO <now in ms>] AND visibleto:[ <now in ms> TO

Could it then be reduced to
(-visiblefrom:[* TO *] AND visibleto:[<now in ms> TO <long max value>])
OR (-visibleto:[ * TO *] AND visiblefrom:[0 TO <now in ms>])
OR ( visiblefrom:[0 TO <now in ms>] AND visibleto:[ <now in ms> TO
<long max value>])
?
Would I gain a lot more speed if I set visiblefrom to 0 and visibleto to <long
max value>. The query would then be:
visiblefrom:[0 TO <now in ms>] AND visibleto:[ <now in ms> TO <long max value>]
And a rather Solr'y question, nevertheless I ask it here:
I intended to use this very query as query filter (qf), but I guess it doesn't
make sense because '<now in ms>' changes at every call ;)

The basic idea seems sound, but I think you can simplify that query a bit. For
one thing, the *:* clauses can be removed in a few places:
also if you index an explicit null value you won't need them at all; for
visiblefrom, if you don't have a from time, use 0, for visibleto, if you don't
have a to time, use maxlong.
