I wanted to know and be shown that the primarykey in the datatable class is indexed for fast queries.
I have alot of queries to do and dont wanna use a datatable unless it has some b-tree or hashtable or something behind the primarykey.  I mean if it just does a linear search then forget it and i will go use hashtable class

I'd forget it and either pull queries from a database - uor use hashtables, the primary key is basically for referential integrity
