However, different databases use different symbols, so check what is used. In truncation the end of the word is replaced.  For example physiother* will retrieve physiotherapy, physiotherapeutic, physiotherapist and so on. In wildcard searching, letters from inside the word are replaced.  For example wom*n will retrieve the terms woman and women. 14
