[vsnet-chat 2608] Re: 'F Type' Carbon Stars

Searching lists is something computer scientists have
been working on for generations.  Using a database
tool is not always the quickest method.  Visier, as
Brian has stated, is designed for such searches and
is probably your weapon of choice.  I build specialized
search engines for specific tasks, such as matching
stars in a given field with previous observations,
and you can usually optimize such searches far better
than with a general tool.  For a very quick example,
just order the big list in RA and index into the list
for each candidate; you then only have a very small
part of the big catalog that has to be searched.
