why Nutch does not? Without this feature Nutch is not too useful.
Nutch currently supports required terms and prohibited terms (equivalent to AND and NOT). That is what most people use. Google did not add support for OR until late 2000, when they were already the most popular search engine. So clearly one can have a useful search engine without OR!

As others have pointed out, it would not be too hard to add support for OR to Nutch, and someday, no doubt, someone will.
