Thank you Chris and Noel, but I am afraid I cannot use your advice, because what I am trying to do is to search "each molecule in the DB as a substructure against all molecules in the same DB", one by one, applying all possible permutations using a script; for this reason I can't decide beforeha

Dear all, I am trying to look for certain molecules in the sdf/fs database containing certain fragments as substructure. The problem is my fragments can be small (I am running a script to do multiple searches), so I can get "too many candidates in the fingerprint search phase". The simple solut
