: It becomes a three clause boolean query...would there be a difference in
: scoring? I assumed not and it used to make a boolean that contained
: another boolean...these days it checks to see if its in a chain of the
: same operator and makes only one boolean.
there is in fact a difference in score ... a big difference depending
on how the coordFactor comes into play. your three-clause approach makes
sense to me as the "right" approach, but your "in a chain of the same
operator" comment scares me ... how does "A | B | C ! D ! E" get parsed?
I would assume it should result in the QueryParser equivilent of
"A B C -D -E" ... is there any way to produce a the same underlying
BooleanQuery using your syntax?
: Just a boolean right now. I will have to look at DisjuntionMaxQuery.
: Currently its just a boolean: +field1:foo +field2:foo
hmmm... so field1,field2(foo) requires that foo match on both field1 and
field2, even if you've used it in this context...
fieldX(bar) | field1,field2(foo)
...it seems like a shortcut for "match on foo in ANY of the following
fields" would be needed in more cases then a shortfut for "match on foo in
ALL of the following fields"

: ':' is for slop on a phrase query. "the car is burning so get out":2
: will allow for each word to be within 2.
: '~' is a binary operator...mark ~4 postman...or say: (mark ~5 (horse &
: car) ~6 tom brady | "hard knocks dude":3) ~6 garbage
:
: Phrase slop could be specified with the '~' op too: the ~2 car ~2 is
: ~burning ~2 so ~2 get ~2 out : but that is a pain in the butt.
you kind of lost me there ... i get that ~ is a binary operator, but in
both cases the intent is to say "these words must appear near eachother"
...s oi'm wondering why you cose to use "hard knocks dude":3 instead of
"hard knocks dude"~3 .... oh wiat, i think i get it ... was it to
eliminate ambiguity of something like ("hard knocks dude" ~3 foo) ...
is the whitespace arround binary operators optional?
