This isn't exactly what you're asking about, but is closely related:   
In addition to "-" and "+" operators, OSMASE (the underlying search  
engine in SPT and CWIS) also supports the "~" operator to indicate  
terms that are not required but should be considered.

This can come in very handy when doing a search that returns a lot of  
records, as it will bring those that mention the optional terms to the  
top (or at least higher in the search results) without discarding  
other records that don't contain those terms but may still be relevant.
