- Full Text search, with Porter Stemming
- Suggested queries. Kennedy recommends other queries if you don't get many results
- Complex search queries. For example: "cats AND dogs", "(cats OR dogs) NOT birds".
- Image Search! Kennedy indexes link text and path info to enable searching for images.
- Content language classification using ngrams instead of MIME types
lang=parameters - PageRank-dervied algorithm to better determine results relevance
- Clean Snippets: Search results include a snippet of content which matches your query. Your keywords are [surrounded] with brackets, and gemtext formatting is removed to make it cleaner to read.
- Lines count: To help you sort quick articles from longer form content, search results tell you how many lines are in the content. If you want to be nerdy, I also include byte sizes.
