> When parsing an rss feed, only one post will be indexed per feed. The reason
> for this is that the digest, which is calculated for based on the content (or
> the url if the content is null) is always the same for each post in a feed.
> I noticed this when I was examining my lucene indexes using Luke. All of the
> individual feed entries were being indexed properly but then when the dedup
> step ran, my merged index ended up with only one document.
> As a quick fix, I simply overrode the digest in the FeedIndexingFilter.java,
> by adding the following code to the filter function:
> byte[] signature = MD5Hash.digest(url.toString()).getDigest();
> doc.removeField("digest");
> doc.add(new Field("digest", StringUtil.toHexString(signature),
> Field.Store.YES, Field.Index.NO));
> This seems to fix the issue as the index now contains the proper number of
> documents.
> Anyone have any comments on whether this is a good solution or if there is a
> better solution?
