in general MQL doesnt yet support 'OR' or full regular expressions.
ideally you should be able to do this with something like the  
following, but it doesnt currently work.
I have filed a feature request for MQL to support this.  MQL-468

[
   {
     "a:name" : {
       "a:value~=" : "^2*",
       "b:value~=" : "^3*",
	...
       "lang" : "/lang/en"
     },
     "limit" : 5,
     "name" : null,
     "type" : "/base/bioventurist/science_or_technology_company"
   }
]
