Thanks, Chris for your clear explanations, it seems there are a lot info
on using Lucene but info for the internal workings of Lucene is hard to
come by.
I got some more questions which I'll ask in-line.

There's actually three possible scorers used: ConjunctionScorer can be
used if all of the clauses are required. Most of the behavior is driven
based on wether or not BooleanQuery.setUseScorer14(true) -- by default it
is false, which means BooleanScorer2 is used.
1) I'm using the default QueryParser to parse and return a query so it's
a Boolean-OR query. So does this mean it uses the DisjunctionSumScorer
or something?
2) Just wondering looking at the API for BooleanQuery i saw this: "Using
setMinimumNumberShouldMatch will force the use of BooleanWeight2,
regardless of wether setUseScorer14(true) has been called."
What is the method setUseScorer14 about?
