If you want specific information, such as information about pharmaceutical sciences Web directories are the way to go, because they search all the contents of a website. Indexes use software programs called spiders and robots that scour the Internet, analyzing millions of web pages and newsgroup postings and indexing all of the words, including pharmaceutical sciences.
Indexes like AltaVista and Google find individual pages of a pharmaceutical sciences website that match your search criteria, even if the site itself has nothing to do with what you are looking for. You can often find unexpected gems of information this way, but be prepared to wade through a lot of irrelevant information too. Our pharmaceutical sciences information is apposite.
Search results may be ranked in order of relevancy eg the number of times your pharmaceutical sciences search term appears in a document or how closely the pharmaceutical sciences document appears to match a concept you have entered. This is a much more thorough way to locate what you want. Alternatively you can go with our pharmaceutical sciences recommendations and save a lot of time.
