Lucene developers, We’ve been working on a undergraduate project to the college about changing Apache Nutch (that uses Lucene do index it’s web pages) to include a category filter, and we are having problems about the query part. We want to develop an application with a good performance, so we thought that here would be the best place to ask this kind of question. The idea is that the user can search pages stored for only a category. So the number of results found should display the number of pages that actually is classified in that category.
The problem is about how to add to the Lucene indexes the category information, and how filter the search on that. We tried to look on the Nutch mailing-list (Nabble) about that and asked some help, but people from there think that we should use some plug-in like Carrot, that get like 100 of pages and classify it in the query time. We are not very confident that it’s the best solution. We thought in other two different ideas: #1 To classify those pages and store that information on a DB and in the query time filter the result that DB to filter the result. #2 Use different index servers, one for each category and one to search without filtering by category. We have seen on this project http://search-lucene.com/ that there are pre-defined categories. We think that this should be classified at indexing time, as we wanted. Do you have any other idea about how to do that?
