NAME

Metabase::Index - Interface for Metabase indexing

VERSION

version 0.008

SYNOPSIS

package Metabase::Index::Bar;
use Metabase::Fact;
use Moose;
with 'Metabase::Index';

# define Moose attributes

sub add {
  my ( $self, $fact ) = @_;
  # index a fact
}

sub search {
  my ( $self, %spec ) = @_;
  # conduct search 
  return \@matches;
}

DESCRIPTION

This describes the interface for indexing and searching facts. Implementations must provide the add and search methods.

USAGE

exists

if ( $index->exists( $guid ) ) { do_stuff() }

This interface provides an exists method that calls search() and returns a boolean value.

for $guid ( @{ $index->search( %spec ) } ) {
  # do stuff
}

Returns an arrayref of GUIDs satisfying the search spec. Exact semantics of the search spec are still under development. At a minimum, a list of key value pairs should be considered to be an "AND" operation testing for equality.

Keys should be keys from core, content, or resource metadata. E.g.

core.guid
core.type
core.resource
content.somefield
