Chapter 6: Query syntax and matching Query expression syntax and matching
6-10 HP StorageWorks Reference Information Storage System User Guide, February 2005
Note: The second alternative syntax for AND indicates that AND is the
default connective in query expressions. You do not need to
supply
AND explicitly. It is assumed if neither AND nor OR is used
explicitly. For example, the query
peace quiet is equivalent to the
query peace AND quiet .
A
NOT expression must be combined, using AND or OR , with another
expression other than
NOT (see Nested Boolean query expressions , on
page 6-11
) . A query cannot consist solely of negative criteria.
You must provide the proper number of arguments for a Boolean operator, or
an error message will result: one argument for
NOT ( - , ! ), two arguments for
each of
AND ( && ) and OR . For example, these queries will each result in an
error message:
• alpha NOT – missing argument for NOT
• AND alpha – missing argument for AND
Boolean operators must be surrounded by one or more separators, typically
whitespace. For example, the query
peas&&carrots is not equivalent to the
query
peas && carrots ; peas&&carrots is a single word ( & is a word character).
