# Search::MultiMatch

[Search::MultiMatch](https://metacpan.org/release/Search-MultiMatch) works by creating a multidimensional hash-table with keys as 2D-arrays, which are stored as nodes.

It accepts matching the stored entries with a pattern, that is also a 2D-array, identifying matches by walking the table from node to node.

```perl
   use Search::MultiMatch;

   # Create a SMM object
   my $smm = Search::MultiMatch->new();

   # Add an entry
   $smm->add($key, $value);                # key is a 2D-array

   # Search with a pattern
   my @matches = $smm->search($pattern);   # pattern is a 2D-array
```

This example illustrates how to add some key/value pairs to the table and how to search the table with a given pattern at a later time:

```perl
   use Search::MultiMatch;
   use Data::Dump qw(pp);

   # Creates a SMM object
   my $smm = Search::MultiMatch->new();

   # Create a 2D-array key, by splitting the string
   # into words, then each word into characters.
   sub make_key {
       [map { [split //] } split(' ', lc($_[0]))];
   }

   my @movies = (
                 'My First Lover',
                 'A Lot Like Love',
                 'Funny Games (2007)',
                 'Cinderella Man (2005)',
                 'Pulp Fiction (1994)',
                 'Don\'t Say a Word (2001)',
                 'Secret Window (2004)',
                 'The Lookout (2007)',
                 '88 Minutes (2007)',
                 'The Mothman Prophecies',
                 'Love Actually (2003)',
                 'From Paris with Love (2010)',
                 'P.S. I Love You (2007)',
                );

   # Add the entries
   foreach my $movie (@movies) {
       $smm->add(make_key($movie), $movie);
   }

   my $pattern = make_key('i love');        # make the search-pattern
   my @matches = $smm->search($pattern);    # search by the pattern

   pp \@matches;                            # dump the results
```

The results are:

```perl
   [
    {match => "P.S. I Love You (2007)",      score => 2},
    {match => "My First Lover",              score => 1},
    {match => "A Lot Like Love",             score => 1},
    {match => "Love Actually (2003)",        score => 1},
    {match => "From Paris with Love (2010)", score => 1},
   ]
```
