Tschebyscheff.
Quasi* map* py: 1989 The resulting documents have publication year 1989.
so: Eur* J* Mat* Soc* cc: 14 Search for publications in a particular source with
a Mathematics Subject Classification code (cc) in 14.
"Partial diff* eq*" ! elliptic The not-operator ! eliminates all results
containing the word elliptic.
dt: b & au: Hilbert The document type is set to books; alternatively: j for
journal articles, a for book articles.
