NAME

slackget10::Search - The slack-get search class

VERSION

Version 1.0.0

SYNOPSIS

A class to search for packages on a slackget10::PackageList object. This class is a real search engine (I personnally use it couple with the slack-get daemon, on my website), and it has been designed to be easily tunable.

    use slackget10::Search;

    my $search = slackget10::Search->new($packagelist);
    my @array = $search->search_package($string); # the simplier, search a matching package name
    my @array = $search->search_package_in description($string); # More specialyze, search in the package description
    my @array = $search->search_package_multi_fields($string,@fields); # search in each fields for matching $string

All methods return an array of slackget10::Package objects.

CONSTRUCTOR

new

The constructor take a slackget10::PackageList object as argument.

        my $search = slackget10::Search->new($packagelist);

FUNCTIONS

search_package

This method take a string as parameter search for packages matching the string, and return an array of slackget10::Package

        @packages = $packageslist->search_package('gcc');

This method take a string as parameter search for packages where the id is equal to this string. Return the index of the packages in the list.

        $idx = $packageslist->exact_search('perl-mime-base64-3.05-noarch-1');

Same as exact_search() but search on the name of the package instead of its id.

        $idx = $packageslist->exact_search('perl-mime-base64');

search_package_in_description

Take a string as parameter, and search for this string in the package description

        my @array = $search->search_package_in description($string);

search_package_multi_fields

Take a string and a fiels list as parameter, and search for this string in the package required fields

        my @array = $search->search_package_multi_fields($string,@fields);

TIPS: you can restrict the search domain by providing fields with restrictions, for example :

        # For a search only in packages from the Slackware source.
        my @results = $search->search_package_multi_fields('burner', 'package-source=slackware', 'description','name');
        
        # For a search only in packages from the Audioslack source, and only i486 packages
        my @results = $search->search_package_multi_fields('burner', 'package-source=audioslack', 'architecture=i486', 'description','name');

take a reference on an array of string (requests) as first parameters and a reference to an array which contains the list of fields to search in, and perform a search.

This method return an array of slackget10::Package as a result. The array is sort by pertinences.

        my @result_array = $search->multi_search(['burn','dvd','cd'],['name','id','description']) ;

You can apply the same tips than for the search_package_multi_fields() method, about the restrictions on search fields.
