/**
* call-seq:
* search(*queries, ...) → an_array
*
* Search the database with POSIX regular expressions for packages.
* === Parameters
* [*queries (splat)]
* A list of strings interpreted as POSIX regular expressions.
* For a package to be found, it must match _all_ queries terms,
* not just a single one. Each query is matched against both
* the package name and the package description, where only
* one needs to match for the package to be considered.
*
* Note that the match is not performed by Ruby or even Oniguruma/Onigmo,
* but directly in libalpm via the +regexp+ library in C.
*
* === Return value
* An array of Package instances whose names matched _all_ regular expressions.
