Allow for searching trough www.hackenkunjeleren.nl (using WP API?)

Would be nice if we can search trough the wordpress site @ https://www.hackenkunjeleren.nl and get article/page results back. First result would be returned to IRC.

There is no API by default it seems, probably best to reuse the !google command but with a 'site:hackenkunjeleren.nl' option prefixed to the query.
