----------------------------------------------------------------

So you mean we should simply kick this new class and use whats already in 
Lucene? I would like this.

I think the idea behind Ryans patch was, to create a Filter using a BitSet and 
do the chaining directly on *one* instance of the BitSet. In my opinion, this 
is not, what the new DocIdSet should do. The Filter chaining should be done in 
the iterator.

Another approach would be to use the BooleanFilter from contrib/search! It has 
all the functionality provided by Ryans class. We would only need to have build 
dependency between contrib/spatial and contrib/queries.

> From erik's comments in LUCENE-1387
>     * Maybe the Filter's should be using the DocIdSet API rather than the 
> BitSet deprecated stuff? We can refactor that after being committed I 
> supposed, but not something we want to leave like that.
> We should also look at moving SerialChainFilter out of the spatial contrib 
> since it is more generally useful then just spatial search.
