Subject [jira] Commented: (NUTCH-775) Enhance Searcher interface
Date Thu, 28 Jan 2010 19:05:35 GMT


Andrzej Bialecki  commented on NUTCH-775:

IMHO this could go as it is ... one suggestion though: this Query/QueryContext now resembles
SolrQuery/SolrParams. Perhaps we could rename QueryContext to QueryParams?

> 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.
