It is possible to combine more than one search, there are two ways you can do this.
The first is to use an AND clause, the second is to use an OR clause.
If you wanted to search for any tenders that contained the words Management AND Consultants then simply enter : Management*Consultants.
However if you were interested in searching for any tenders that contained the word Management OR the word Consultant then simply enter Management,Consultants.
It is also possible to combine the two together.
For instance if you were interested in finding tenders for Computer Training OR Computer Courses then enter Computer*Training,Courses (Computer AND Training OR Courses).
