Sure, but let me ask you, do you like working with those people who
are jerks all the time?
You are completely off-base in regards to my Columbia reference.
It is sorrowful when anyone dies (others would dispute this,
executions of murderers, etc.), but people die all the time - it
doesn't make it a tragedy.
What makes the Columbia truly a tragedy is that they died due to
Also, ideally my coworker would be both. But given that people are of
differing ability levels, my coworker has a problem. If he is smarter
than me, wasting his time explaining things over and over to me does
little good - unless I take the time to learn from it - and that is
not always
Robert, if you wish to continue on this list I suggest you stop.
Either contribute peacefully and positively to this list or you will
be removed. We've all had it with your name calling and constant
derision backed up by a complete lack of substance in actually doing
any of the work,
Can we please let this thread die.

Thinking out loud,
SSD is pretty close to RAM when it comes to seeking. Wouldn't that
mean that a bitset stored on an SSD would be more or less as fast as a
bitset in RAM? So how about storing all permutations of filters one
use on SSD? Perhaps loading them to RAM in case they are
While SSDs are delightfully fast compared to mechanical drives, I
think they are still quite a bit slower than RAM for truly random
access.
EG Intel's X25-E (apparently the leader at the moment) lists a 75us
read latency, whereas RAM latency is maybe 50-100 ns.
Though since Lucene accesses the

Provided that your index can fit in the system i/o cache and stay there,
If your index can fit in the IO cache, you should using a completely
different implementation...
You should be writing a sequential transaction log for add/update/
delete operations, and storing the entire index in memory
(RAMDirectory) - with periodic background flushes of the log.

I have better things to do than read a 10,000 word incident that discusses about 100 different topics under the generic heading "Further steps towards flexible indexing" in order to answer a simple question.You are a moron. And I don't mean that in a offensive way - I am using the secondary

That's still offensive and totally unacceptable here. Please refrain
from making ad-hominem remarks and stick to discussing the issues.

Your exactly right. Playing well with others has trumped actual
production and quality. You can see the mess that's gotten us in all

It was not ad hominem. It was a indirect critique of the value of the
answer provided.
Ad hominem would be if I called him ugly.
