| Summary : Fast search for very large numbers of keys in a body of text
|
Description :
This module provides facilities for fast searching on strings with very
many search keys. The basic object behaves somewhat like a perl hash,
except that you can retrieve based on a superstring of any keys stored.
Simply scan a string as shown above and you will get back a perl hash (or
list) of all keys found in the string (along with associated values and/or
positions). All keys present in the text are returned.
There are several ways to influence the behavior of the match, chiefly by
the use of several types of *global character classes*. These are different
from regular expression char classes, in that they apply to the entire text
and for all keys. These consist of the \"ignore\" class, the \"boundary\"
class, the \"inclboundary\" class, and any user-defined classes.
Using \"ignore\" characters you can have the scan pretend a char in the text
simply does not exist. This is useful if you want to avoid tokenizing your
text. So for instance, if the period \'.\' is in your \"ignore\" class, the
text will be treated exactly as if all periods had been deleted.
To define what characters may count as the delimiter of any match (single
space by default) you can use the \"boundary\" class. For instance this way
you can count punctuation as a boundary, and phrases bounded at the end by
punctuation will match.
Any user-defined character classes can be used to count different chars as
the same. For instance this is used internally to implement
case-insensitive matching.
About unicode/utf8 strings. Text::Scan acts at the octet level so it\'s not
aware of anything about unicode/utf8 encoded strings. If you deal with such
strings, it\'s recommended to give octets strings to Text::Scan using
Encode::encode_utf8(). Text::Scan will then give you back octets strings ,
utf8 encoded found keys.
