Thanks

Quick question. I modified my template to add 'Omnibus' to the beginning of the list for easier searching. Lines 3-12 and 29-30:

program:

## Checking for omnibus
	if 
		'omnibus' 
	in 
		$#admin_tags 
	then 
		omnibus = 'Omnibus' 
	else 
		omnibus = ''
	fi;

## Splitting tags
	if 
		'^(Fiction|Nonfiction|Magazines & Periodicals)' in $#booktype 
	then 
		split_tags = re($tags, '\.', ',') 
	else
		split_tags = ''
	fi;

## Removing a few unwanteds and sorting
		cleaned_tags = list_sort(list_difference(
			split_tags,
			'Fiction, Nonfiction, Magazines & Periodicals, Cultures & Regions, Social Issues',
			','), 0, ',');

## Last runthrough
	cleaned_tags = list_union(cleaned_tags, omnibus, ',')

two questions:


a) Why does list_union seem to work in reverse? (e.g. if I put 'omnibus' first in template, it appears at the end of the list).

b) Currently, an icon rule checks #admin_tags for 'omnibus.' Would there be any performance impact by checking the composite column instead?

Thanks and merry christmas (or whatever you celebrate)
