Boolean search now available

[N. J. A. Sloane]

One of the troubles with the "lookup" page has always
been that you could only look up one word or phrase.

So if you wanted to know which sequences mentioned
"Chess" in the subject line, and "Elkies" in the
reference line, you had to make two separate searches
and combine the results by hand.

There is now a new "Boolean" search, that will let you
specify TWO words or phrases!

You can search for 
P AND Q,  P OR Q,  or  P BUT NOT Q

The program is ready for testing by friendly users.

At present it is in a new advance search page, 
http://www.research.att.com/~njas/sequences/index3.html

When all the bugs are out it will be merged in with
the regular advanced search page,
http://www.research.att.com/~njas/sequences/index2.html

Comments are welcomed.

Some things you can do with it:

Find sequences that mention both A012345 AND A001105

Sequences with keyword "uned" AND XXXXX

Sequences that mention "knight" OR "chess"

Sequences that mention "code" (but) NOT "Hamming"
