...
The answer to all of your questions is yes, however documents marked for
deletion are also "removed" from segments whenever they are merged, which
can happen on any add.

We're trying to perform a query where if our intended search term/phrase is
part of a specific larger phrase, we want to ignore that particular match,
but not the entire document (unless of course there are no other hits with
our intended term/phrase). For example, a query like:
"white house"
No. Its just a simple number of terms taken from the document limiter used
on the assumption that text that long stops adding value, or starts adding
noise, or starts accelerating into diminishing returns at that point. No
optimizations are used based on it.

The gist is: it doesn't help. That simply cuts long documents off at the
knees on the assumption that its long enough already, that more won't
add much value (and may add noise?). Its not used for any sort of
optimizations...its a straight, just use the first n tokens from a document.

tx for the response but i think i didnt make my question clear...
If i am indexing a filed that can at the max contain 1000 fileds, does it
help in improving performance if i let Lucene know IN ADVANCE about 1000?

The documentation for delete operation seems to be confusing (i am going
thru the book and also posted in the books forums...), so appreciate if
someone can let me know if my below understanding is correct.

You can simply change your input string to lowercase before passing it
to the analyzers, which will give you the effect of escaping the boolean
operators. (I.E you will now search on and or and not) Remember
however that these are extremely common words, and chances are high that
you are remo

as of the last time i checked: no, they're baked into the grammer.
(that may have changed when it switchedfrom a javac to a flex grammer
though, so i'm not 100% positive)

it works!! Thanks
I believe Highlighter.setMaxDocBytesToAnalyze(int byteCount) should be used
for this.
