To search for expressions which include spaces, use the hash/pound symbol (do not use quotes)
eg. le#pen will return matches for both Le Pen and LePen
Boolean operators also work. Words are AND'ed together by default.
eg.
serbia croatia will return all threads which mention both countries
serbia or croatia will return threads which name either
serbia and not croatia (or serbia -croatia) will return matches which mention one but not the other
The asterisk wildcard also works
eg. com*uter will return matches to both computer and commuter
It can also be combined with the boolean operators: com*uter and not computer will have the same effect as just searching for commuter
A useful trick for searches shorter than the 4-letter limit: append an asterisk
eg. CIA* (but beware this will also return any words beginning with cia)
