hi Masi,
sounds interesting, i'm not sure how this can be handled. Storing search
results in a session is quite easy, but how do you present this on pages ?
Storing search result in tables may be a good idea, but it sounds nearly
same like creating cHashes for piVar-combinations.
Can you give us a deeper thought of this ?
