Date Wed, 30 Dec 2009 19:09:29 GMT

Sami Siren updated NUTCH-775:
-----------------------------

    Attachment: NUTCH-775.patch

I ended up changing the Query API instead since the changes were smaller from API perspective
that way.

> Current Searcher interface is too limited for many purposes:
> Hits search(Query query, int numHits, String dedupField, String sortField,
>       boolean reverse) throws IOException;
> It would be nice that we had an interface that allowed adding different features without
changing the interface. I am proposing that we deprecate the current search method and introduce
something like:
> Hits search(Query query, Metadata context) throws IOException;
> Also at the same time we should enhance the QueryFilter interface to look something like:
> BooleanQuery filter(Query input, BooleanQuery translation, Metadata context)
>     throws QueryException;
> I would like to hear your comments before proceeding with a patch.
