The list of the domain names from the exploration
of the DNS records is sorted according to the combined
citation weights of the web pages, which contain the
incoming links to these domain names. For the search
through this list, you may use the regular expressions.
There are two main types of the results, the domain
names with the _for-sale DNS records, and the domain
names without any DNS records, which indicates, that
the detailed human exploration may be useful.

This list is divided into many baskets, in order to
ensure, that the search will be nice for the resources
of the machine. The domain names with the best incoming
links are placed into the basket # 0 (zero). These baskets
are combined into the sagas, according to the times of the
explorations. These times are shown for every basket. For
every domain name, here is shown the combined citation
weight of the web pages with the incoming links to
this domain name, the quantity of such web pages,
and the quantity of the unique host names,
where these web pages are located.

I think about the verification of the status
for the domain names, but I doubt, that the ratio
of the results to the resources will be reasonable.
First, such verification is not reliable. Second,
even when the domain name is available for
the registration, the registry may consider this
domain name as premium, then the price of
the registration is quite expensive. The quantity
of the useful domain names is much less, than
the total quantity of the domain names, thus,
the human verification is more reasonable.
