So Google Blog Search has changed the way it indexes content.

Instead of  indexing content from RSS feeds, the search now focuses on full content from pages.

According to those in the know at Google the indexing change has “improved the results for a lot of queries, both because we have the full content of the page and because we extract links that are missing from the feeds”.

But change rarely comes without a niggle or two. Some users have reported problems in a Google Groups post when a person’s blog name drew results based on blogroll content, too.

The Google team member does admit that “there have been occasional complaints about the use of the feed content, particularly the problem with partial feeds”.

Google also revealed that it had expected some problems from blogroll matches, but that they “may have underestimated the impact on searches using the link: operator or where the query matches a blog or blogger’s name”.

However, Google is working on fixing this glitch and plans to use the full-page content for searches, but exclude the content that isn’t actually part of the post.

The search engine supremo is hoping to have the problem sorted by the end of this year.
