snippet syntax questions

[ColoradoHomeFinder]

Just a quick question about using snippets. in this example #idx-sample#

How do i enter multiple subdivisions?

I think i'm using incorrect syntax - on this note any white paper or tech bulleting on how to overall syntax use for snippets.

Can i get a complete list of available idx fields for metrolist that can be used in snippets?

To search for multiple subdivisions, you would use:
$_REQUEST['search_subdivision'][] = 'your 1st subdivision name';
$_REQUEST['search_subdivision'][] = 'your 2nd subdivision name';
etc.
