Given a keyword or a pattern, the search method will scan the tree to find a value, a description or anything that match the given pattern (or keyword). Constructor new (type => [ value | description ... ] ) Creates a new searcher object. The "type" parameter can be: element value key summary description help all Search in all the items above Methods search(keyword) Search the keyword or pattern in the tree. The search is done in a case insensitive manner. Returns a list of path pointing to the matching tree element. See "grab(...)" in Config::Model::AnyThing for details on the path syntax.BUGSCreating a class with just one search method may be overkill. OTOH, it may be extended later to provide iterative search.AUTHORDominique Dumont, (ddumont at cpan dot org)SEE ALSOConfig::Model, Config::Model::SearchElement, Config::Model::AnyThing perl v5.14.2 2012-11-09 Config::Model::TreeSearcher(3pm)
