You can find more information on the speaker's site:


Default action of generic text search fields on many sites is just looking through available text content and making some assumptions on how to sort the results.

I'd like to talk about special part of such user friendly search features, which are (not widely) used in Google and other world-wide search engines.

On the example of whoyougle.com site I will demonstrate how we handle text queries, how we make parallel subrequests, how we collect results and how we involve Gearman job server.

* Issue parallel jobs
* Collect results
* Combine results so they look smart
* Using Geamand
* Writing compilers and parsers for text queries

I will also briefly show similar aspects of how wolframalpha.com brings their results from API requests.

The talk is intended for anyone who's fund of text processing in Perl and search technologies in general.

As an addition, I will demonstrate the process of creating the grammar in Perl 6 language to parse currency converter.
