I expect you'll need to do some pre-processing. Read in your text into a

Hi all,
Just been playing with Digester after reading chapter 7 in LIA. Seems to fit
my needs as I have a relatively simple XML structure.

Hi,
Seems like an odd request I'm sure. However, my application relies an index,
and should the index become unusable for some unfortunate reason, I'd like my
app to gracefully cope with this situation.
Firstly, I need to know how to detect a broken index. Opening an IndexReader
can potentiall

If you're indexing many documents which contain multiple languages then it's
probably just better to use a SimpleAnalyser, rather than one that does any
language s
ser to specify their input language because otherwise,
results will be poor.

Can you not provide the user with a option list to specify their input
language?
Language identification can be a pretty tricky field. There are some tricks
you can do with unicode to identify language, e.g., \u0600 - \u06FF contains
the Arabic characters, so if you're input contains lots of ch

Hi,
I've been using Lucene for a few months now, although not in a typical
"building a search engine" kind of way*. Basically, I have some large
documents. I would like a system whereby I search for a term, and then I
receive a hit for each match, with its context, e.g., ten words either side
19 matches
