Hi, We are pleased to announce the next major release 2.1 of Hayoo!, the Haskell API search engine with find-as-you-type and suggestions. Visit Hayoo! here: http://holumbus.fh-wedel.de/hayoo What's new? Thanks to Uwe Schmidt, we have completely revamped the indexer, which now also crawls package information from Hackage. Hence, Hayoo! now searches package names, package categories, package descriptions etc., too, and shows you some package results along with the functions found (some of you may have noticed this already, since this is live for testing purposes since a few months). For example, this will find you all packages in the category "Algorithms" that will do something with "sat": category:algorithms sat This will find you some strict datastructures (i.e. synopsis contains "strict" and category contains "data"): synopsis:strict category:data As we now have package information present in the search index, the algorithm for ranking the results has been adjusted to mainly depend on reverse package dependencies. Nevertheless, we are still trying to optimize this. The new indexer also supports incremental index updates, which made a rebuild of the whole infrastructure around it possible. This way, we are now able to provide daily index updates. Useful figures about the current index are shown below the query input field. Additionally, we have made some optimizations and performance improvements. This allowed us to leverage the restrictions on the query length and hence it is now possible to search for any single character (try searching for "s"). In the result display, the whole function description is now included and its formatting is preserved. Internally, the HTML rendering part has been completely rewritten, which hopefully allows for faster adoption of new features. Please let us know about any issues or suggestions. Especially some opinions about how to integrate the package information in the result display would be appreciated. Thanks, Timo
