One thing that I know has bogged me is when matching a phrase where I
would expect mathematical formula (which is "just a subphrase"). I
would have liked the phrase-query to extend as far as it wishes but not
passed a given token... would this be possible ?
Presumably a period token and this feature would have provided the same?

Hi,
Was wondering what people's experience is with storing sentence (or
other) boundary information in Lucene. For instance, for phrase
queries, you may not want to match when two terms lie on either side
of a sentence boundary. I know for phrase queries the common approach
is to make the position increment larger than one, which solves that
immediate problem, but I have other uses for such information, too.
Should I just store some type of boundary marker at the appropriate
position and check to see if I have a boundary marker when doing my
processing? I know I need an Analyzer that can detect the boundaries,
for starters. What other issues have people run up against?
Thanks,
Grant
