can help you do grouping and sorting, etc. But if you
still want to achieve it using lucene, you might want to post some code so
that I can go through it and see why it uses so much resource then.

Check out Filter class. You can create a separate filter for each field and
then chain them together using ChainFilter. If you cache the filter, it will
be pretty fast.

Running a profiler is still the best advice I can think of. It should
clearly show you what is going on when you run out of CPU.

Greetings All,
I have been trying out Lucene recently and very happy with the search
performance. But just notice that when Lucene performing search or index,
the CPU usage on my machine raise to 100%, because of this issue, some of my
others backend process will slow down eventually. Just want
esults from the
different indexes, which may or may not be difficult.
Hope this helps

every month, many of your concerns disappear. If it needs to be
updated every 5 seconds, it's another matter entirely.
So which is it?

Once you have numbers, you can make better decisions
And people can give you better advice, especially if you
include more detail of your design.

Hi, I’m a new user to Lucene, and heard that it is a powerful tool for full
text search and I’m planning to use it in my project for data storage
purpose. Before the implementation, I could like to know whether there is
performance issue on Lucene indexing process. I have no doubt on the
