Re: Faceted Search: count direct matches/member für result nodes

Good Morning, thank you very much!! I got it so far, that the result changed by using the different ordinal policies, but they're not correct so far. I think it does not work, because one lucene document can have one or even more categories in my indexing routine and I think this causes faulty

Re: please help

Java is telling you the issue there. You're trying to cast a StandardDirectoryReader to an AtomicReader. I think AtomicReaders are per segment readers and in this case you actually want to get a view of all the terms in the index (i.e. over all segments), so I think you could wrap the reader you ha

Common Index with personalized fields

We have a system where N number of users are tied to a particular lucene index. Sort of "Shared Index". But each of the N users can have their own personalized fields. Ex: Every E-mail to lucene mailing-list is a document Every user part of this mailing-list has his own set of labels for tha

Re: Difference between Group and Facet

Hi, I'm not sure what you mean with how to index a group. You basically index all documents, and then group them for the results. To stay on the books example: you index books including information about the author. So each document in the index is a book. But in your result list, you want to displ

Re: Faceted Search: count direct matches/member für result nodes

Hi To override OrdinalPolicy you need to do the following: FacetIndexingParams fip = new FacetIndexingParams() { public CategoryListParams getCategoryListParams(CategoryPath) { return new CategoryListParams() { public OrdinalPolicy getOrdinalPolicy(String) {} } } } BTW, in the

Hi, I wasnt able to find any guidelines on how to add a Group while indexing. There is a user guide and demo code for Facet which shows this. Can you please show how to add a Group while indexing? Thanks, Rajesh On Mon, May 27, 2013 at 3:55 PM, raj wrote: > Hi Elisabeth, > > Thanks. Let me go

Difference between Group and Facet

Hi, I was seeing that Lucene supports both Groups and Facets. But I was finding it difficult to understand the difference between both. https://issues.apache.org/jira/browse/LUCENE-1421 - Says "Ability to Group search results by Field". So, is this by existing Fields that we add while indexing or
