|MassLib is built in full awareness that a single search aspect (such
as the identity of a spectrum) is unsufficient to reflect the complex reality
(background, partial and full coelutions, weak intensity of important compounds,
almost identity of spectra of chemicals with different structure, unknowns
with no reference spectrum in the libraries). A search hitlist is a one
dimensional arrangement. The real search problems are multidimensional.
A variety of hitlists, provided they result from sufficiently independent
search procedures, are more promising to contain valid information in the
combined first ranks of the respective onedimensional hitlists. And the
bigger the general purpose database is, the higher is the probability to
find some at least partial structurally related stuff in it...
