Question

I’m taking over a project so I’m still learning this. The project uses Lucence.NET. I also have no idea if this piece of functionality is correct or not. Anyway, I am instantiating:

var writer = new IndexWriter(directory, analyzer, false);

For specific documents, I’m calling:

writer.DeleteDocuments(new Term(...));

In the end, I’m calling the usual writer.Optimize(), writer.Commit(), and writer.Close().

The field in the Term object is a Guid, converted to a string (.ToString(“D”)), and is stored in the document, using Field.Store.YES, and Field.Index.NO.

However, with these settings, I cannot seem to delete these documents. The goal is to delete, then add the updated versions, so I’m getting duplicates of the same document. I can provide more code/explanation if needed. Any ideas? Thanks.

The field must be indexed. If a field is not indexed, its terms will not show up in enumeration.
