Views filter and taxonomy synonyms

It's a little different than what you're asking for but I've used synonyms for arguments before. It's a little bit of a hack, but I wanted a way to use taxonomy terms in a URL without having to put + signs where there are spaces. Using synonyms allowed me to display a term like "American Literature" properly in the view's title with spaces and capitalization, but also use a URL like /subjects/americanliterature instead of /subjects/american+literature.

Here's the code I used in the argument handling code section:

if (isset($args[0])) {
 // fetch terms based on the argument in the URL
 $query = "select term_synonym.*, term_data.name as termname from term_synonym left join term_data on term_synonym.tid = term_data.tid where term_synonym.name = '". $args[0] ."'";
 $result = mysql_query($query);
 $data = mysql_fetch_assoc($result);

 if (!empty($data['termname'])) {
   // if the argument is a synonym for another term, use the term's proper name
   $args[0] = $data['termname'];
 }
 else {
   // if there's no term with this synonym, than it must be just a regular term name
   $args[0] = ucwords($args[0]);
 }
}

return $args;

Use the synonyms module to enable search indexing of synonyms and then use the search index filter in views. I think this may work.
