Apologies but there is a known bug in Discover in which using wildcard operators '#' or '?' when searching does not yield more results as it should, eg:

kw: organise - 20,800 

kw: organize - 8,600,000 

kw: organi#e - 33,900 (# replaces 1 character) 

kw: organi?e - 75,300 

Apologies for an inconvenience, unfortunately there is no workaround, but the suppliers have prioritised a fix. 

Truncation searching is unaffected, eg connect* retrieves connect, connection, connectivity, etc.
