Even with all this grim news, the U.S. Department of Agriculture's chief economist wrote in an April 16 blog post that the department's data indicated that "the U.S. agricultural market will remain well supplied and food will continue to be affordable." Even so, the still-escalating crisis clearly has put stress on the supply chain that normally enable foodstuffs to get from farm fields to Americans' dinner tables, and do it so efficiently that many of us probably barely even think about where our usual bountiful supply of fresh fruit, veggies, meats and countless varieties of pasta and breakfast cereal comes from. Even fast food giant Wendy's had to pull burgers and other beef dishes from the menus of nearly 1,000 of its restaurants because of a meat shortage, while Beyond Meat, the plant-based alternative to beef, reported skyrocketing first quarter sales increases of 141 percent. Additionally, as shutdown orders deter Americans from dining out, the surge in demand for food that can be prepared at home - and the difficulty of making it available to consumers while maintaining social distancing - has compelled grocery stores to revamp their way of doing business on the fly. Each time you enter a keyword search, results appear almost instantly thanks to that index. Without it, the search engine would literally have to start searching billions of pages from scratch every time someone wanted information, a process that would be both unwieldy and exasperating. But search engines can't see data stored to the deep Web. There are data incompatibilities. Technical hurdles that complicate indexing efforts. There are private Web sites that require login passwords before you can access the contents. Crawlers can't penetrate data that requires keyword searches on a single, specific Web site. There are timed-access sites that no longer allow public views once a certain time limit has passed. All of those challenges, and a whole lot of others, make data much harder for search engines to find and index. Keep reading to see more about what separates the surface and deep Web. As we've already noted, there are millions upon millions of sub-pages strewn throughout millions of domains. introvertido
