Re: [Lucene.Net] Excluding search results

[João Prado]

I faced the same problem and my approach was encapsulate the result 
TopDocs in an YourObject and then remove/filter the undesirable ones 
using Linq:

        public IQueryable<YourObject> Search(string searchQuery)
        {
            TopDocs topDocs = 
Searcher.PerformSearch(GetIndexSearcher(), searchQuery);

            List<YourObject> list = new List<YourObject>();

            foreach (ScoreDoc scoreDoc in topDocs.scoreDocs)
            {
                Document doc = GetIndexSearcher().Doc(scoreDoc.doc);
                float score = scoreDoc.score;

                list.Add(YourObjectWrapper.Wrap(doc, "venda", score));
            }

            return listaImoveis.AsQueryable();
        }

    public static class YourObjectWrapper
    {
        public static YourObject Wrap(Document doc, float score)
        {
            YourObject yourObject = new YourObject(doc.Get("Id"));
            yourObject.ResultScore = score;

            return yourObject;
        }
    }

We'd like to have the ability to exclude items from a search given the 
ID (the ID is a link between a database for frequently updated 
information and the index for searching).

Optimally, it'd be great if we could just run the query vs the index 
AND the database, but I haven't found anything for doing that (using 
SQLite).

Would this be a custom Filter?  I've dealt with custom analyzers in 
the past, but that wouldn't be useful here.  Is there an existing 
filter where we can say "ignore these documents?"

Thanks in advance.
