| means OR (slower), \b matches a
word "boundary". Accented characters (Umlauts etc.) are not found;
see accent for some tricks.
pattern finds ------- ------------------------------------------ ring ring rings bring string scattering Springer etc. \bring ring rings (but not: bring scattering Springer or string) ring\b ring bring string scattering (but not: rings or Springer) \bring\b ring Ring RING (but not: rings bring etc.) algebraic sy algebraic systems algebraic symbols etc. modu|gauss unimodular Gauss gaussian etc. [NO extra spaces around | ]The more complicated pattern:
lie algebra|cohomology|deformation
locates all books with any of "representation", "Lie algebra", "cohomology",
or "deformation" in their title or as their subject.
If you also enter a second pattern, the (faster) search
will match only if BOTH patterns are found. For instance if the first
pattern is riemann and the second pattern is
geometry , then it will only match entries in which both
riemann AND geometry occur somewhere (case
insensitive always). This runs faster if the least likely
pattern is placed first. Thus, riemann AND
geometry runs faster than geometry AND
riemann.
poincar and hler might be
used for Poincaré or Kähler.\S*. Thus
search for poincar\S* and k\S*hler This
procedure will even catch versions such as Kaehler where an
additional letter has been used..
