Liddy: How a Search Engine Works

I know the Internet, but not about the ‘intranet’. I know the prefix ‘intra’ has to do with ‘within’ a noun, in this case, the Web. Isn’t a finding engine and a search engine the same thing essentially? Document processors have multiple tasks to perform which are impressive technically. I never heard of stop words before. ‘Metatags’ and ‘metadata’ are about themselves to the tee. Each task of the document processor is elaborated. Under the             query processor is ‘tokenizing’. That sounds like a made-up word, the root being ‘token’. If many words have multiple meanings, according to Libby, they are described as ‘polysemous’. I just thought they were ambiguous and synonymous words.
