In recent (very recent actually) times it has come to mean a term
which gives very few (ideally one) hit on an exhaustive search engine
(such as AltaVista).
For instance "hapax legomenon" doesn't qualify, because
http://www.alltheweb.com/cgi-bin/search?query=%22hapax+legomenon%22
gives 223 hits, whereas "LLM-105" would, since giving only five:
http://www.altavista.com/cgi-bin/query?q=LLM-105&search=Search&r=&kl=XX&stype=&pg=aq&text=yes&d0=&d1=
So, if you want to have your stuff found without knowing where it is,
use a neologism (which hopefully doesn't catch on) as marker, and let
the site be indexed by a search engine.
