[Haskell] ANN: Hayoo! 2.1

["Timo B. Hübel"]

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.

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
