BlocksWpQuery::get_cached_posts() public WC 1.0

Get cached posts, if a cache exists.

A hash is generated using the array of query_vars. If doing custom queries via filters such as posts_where (where the SQL query is manipulated directly) you can still ensure there is a unique hash by injecting custom query vars via the parse_query filter. For example:

add_filter( 'parse_query', function( $wp_query ) {
	 $wp_query->query_vars['my_custom_query_var'] = true;
} );

Doing so won't have any negative effect on the query itself, and it will cause the hash to change.
