Query expression syntax and matching

6-6 HP StorageWorks Reference Information Storage System User Guide, February 2005

This set covers western, central and eastern European languages, as well as

Russian and Turkish. The great majority of text in Chinese, Japanese, and

Korean is covered by these character sets as well.

Matching words

Matching of words is not case-sensitive:

cat

Cat

cAt

, and

CAT

all match each

other. Corresponding uppercase and lowercase letters, such as

and

, are

treated the same in all respects.

There are two kinds of query words: words that contain occurrences of one or

both of the

wildcard

characters

and

, and

literal words

that do not contain

wildcards.

A literal word in a query expression matches the same word, character for

character (case ignored), in an archived document. A word with wildcard

characters (

) matches a document word in the same way, character by

character, except:

• ?

– matches any single character in a document word. For example,

b??t

matches

beat

beet

boat

blot

best

bust

bout

, and so on.

• *

– matches any sequence of characters in a document word, including a

sequence of no characters. For example,

f*t

matches the document

words

foot

feet

fit

fault

, and

;

matches any document word beginning

with

You can use any number of wildcard characters (

) in a query word, but

you cannot use a wildcard at the beginning of a query word. For example,

*ion

is not a valid query.
