We don't search for "Dark Matter" we search for "candidates for dark matter" i.e. stuff we didn't know before that could be what is filling the mass discrepancy.
So when a "new" thing is detected it needs to be identified, quantified and analysed to see if it fills the "hole" "dark matter" leaves us.
Once we find it, it probably won't be called dark matter any-more, it will be "gluoninos" or "sprotons" or "Gionottis"
Of course "dark matter" may end up being 5 completely different things.
