Subject Re: Warm up IndexReader

There's no magic to it - just build a query or six and fire them at
your newly opened reader.  If you want to put the effort in you could
track recent queries and use them, or make sure you warm up searches
on particular fields.  Likewise, if you use Lucene's sorting and/or
filters, it might be worth adding them in to the mix as well.

Start simple and stop when you've found something good enough.
