Top Forums Shell Programming and Scripting Can't quite understand this regex Post 302271915 by Christoph Spohr on Monday 29th of December 2008 04:01:01 AM

Hi,

as regards the '^[^:]" your reasoning is right.
But "*" means zero or more occurence, thus a
no-match is a match, too.

So "'^[^:]*::'" matches the "::" part and the "^[^:]" part goes
unrecognised and consequently your term is matched.

HTH Chris

Plucene::Search::TermQuery(3pm) 			User Contributed Perl Documentation			   Plucene::Search::TermQuery(3pm)

NAME
Plucene::Search::TermQuery - a query that contains a term SYNOPSIS
# isa Plucene::Search::Query $term_query->normalize($norm); my $ssw = $term_query->sum_squared_weights($searcher); my $as_string = $term_query->as_string($field); DESCRIPTION
A query that matches a document containing a term. Term query are the simplest possible Plucene queries and are used to match a single word. Term queries are represented by instances of the TermQuery class and contain the desired term (word) and a field name, both are case sensitive. The field specified in a Term query must be a document field that was specified as 'indexible' during the indexing process. If the field was specified during indexing as 'tokenized' than the term will be matched against each of tokens (words) found in that field, otherwise, it will be matched against the entire content of that field. A term query may have an optional boost factor (default = 1.0) that allows to increase or decrease the ranking of documents it matches. METHODS
term / idf / weight Get / set these attributes sum_squared_weights my $ssw = $term_query->sum_squared_weights($searcher); This will return the sum squared weights for the passed in searcher. normalize $term_query->normalize($norm); to_string my $as_string = $term_query->as_string($field); perl v5.12.4 2011-08-14 Plucene::Search::TermQuery(3pm)
