I just had a user search for a screw and put '2' in the Length field.  His search returned hits that had 2" (what he wanted) but also 1/2", 1-1/2", 2-1/4", 2-1/2", 2-3/4", etc.  Basically every part that had a 2 anywhere in the Length field.  This is cool when you're not sure exactly what's in the field and you just want to get close, but often it's very handy to do an exact match search.

As near as I can see, a custom search field (edit field on a search card) has no capacitiy for changing the style of search, so the only option would be to use a NOT wildcard (or a NOTHING wildcard) to exclude search results that don't exactly match the text entered.

What options are available (hope, hope) for increasing the specificity of my search results?
