NAME
       DBIx::SearchBuilder::Union - Deal with multiple SearchBuilder result
       sets as one

SYNOPSIS
	 use DBIx::SearchBuilder::Union;
	 my $U = new DBIx::SearchBuilder::Union;
	 $U->add( $tickets1 );
	 $U->add( $tickets2 );

	   printf "%5d %30.30s\n", $z->Id, $z->Subject;
	 }

WARNING
       This module is still experimental.

DESCRIPTION
       Implements a subset of the DBIx::SearchBuilder collection methods, but
       enough to do iteration over a bunch of results.	Useful for displaying
       the results of two unrelated searches (for the same kind	of objects) in
       a single	list.

METHODS
   new
       Create a	new DBIx::SearchBuilder::Union object.	No arguments.

   add $sb
       Add a searchbuilder result (collection) to the Union object.

       It must be the same type	as the first object added.

   First
       Return the very first element of	the Union (which is the	first element
       of the first Collection).  Also reset the current pointer to that
       element.

   Next
       Return the next element in the Union.

   Last
       Returns the last	item

   Count
       Returns the total number	of elements in the Union'ed Collection

   GotoFirstItem
       Starts the recordset counter over from the first	item. the next time
       you call	Next, you'll get the first item	returned by the	database, as
       if you'd	just started iterating through the result set.

   IsLast
       Returns true if the current row is the last record in the set.

   ItemsArrayRef
       Return a	refernece to an	array containing all objects found by this
       search.

       Will destroy any	positional state.
