Boolean search now available

[N. J. A. Sloane]

James Sellers also suggested that it would
be nice to have the names of the sequences.
However, this would actually take a lot more work
(which is why i haven't implemented this type
of search before)

Yes, the index entries do clutter up the replies, but 
1.  with the Boolean search there are now no duplicates
and
2.  you can search for   Latin square  NOT  Index entries
