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 p

for the last days I had the thought lingering in my mind that somehow I had to use the

However, it's a update-happy application and the index needs to be persistent (meaning
