Storing information

Hi,

I am using Lucene to perform searching. I have certain information that will
be loaded everytime a search is run. This means, if there are multiple user
running the search at the same time, the information will be loaded multiple
times.

This is not effecient at all, so I was wondering is there anyway I can load
those values only once, and every search perform after that no matter how
many user will simply refer to the preloaded values?

Thanks

Is this a Lucene question?
Anyway, refer to the Lucene FieldCache for an example of how to avoid
multiple threads from creating more than one cached object.

You may also want a Document cache and or even a Query cache,
depending on your situation.
