Improvements to indexing and searching

Over the past few months we have been working through our "would be nice" list of improvements. Among the recent changes to the indexer and search engine are:

• Better support for common HTML mistakes, such as unterminated tags and misformated date meta tags.
• Improved date sorting. Previously, documents older than a few years were grouped together.
• Expanded support for structured data, including tel: and mailto: protocols.
• Further refinement of the weighting function to generate more relevant result lists.

We have also been enhancing the tools for visualizing the contents of an index. To see the tools available, log in to the Blossom site and look for the Actions section at the bottom of the Settings page.
