What is a search engine spider? A search engine spider is a software program, which follows the hyperlinks on websites and searches the Internet again and again for new content and new websites. The recorded web sites are then included in the index of the search engines. Further names for search engine spiders are web crawler, bot, robot, or simply, spiders.

How does a spider work? A spider is, in principle, nothing more than a web browser that works automatically and follows all the links on the web. After a website’s pages have been searched automatically, the use of (secret) algorithms determines where in the index the corresponding page is recorded in relation to a particular search term. If this search term is then searched inside a search engine, the user is shown the previously created index. That is, the search engine does not search at the moment of the search, but rather it displays the results from a previous index (which might be outdated).
When creating websites, spider information can be provided. These are located in the head area of the html page and include things like keywords, the title of the page, an indication of how often the spider should visit the site, etc. The extent to which these details are actually taken is unclear. The term “search engine ranking” refers to the specialized language of online marketing, in which results found for a specific query are displayed by a search engine such as Google or Yahoo.
In particular, a search engine ranking can also mean the placement of a single website, which is in the list of search results. It is then said that a website’s search engine ranking should be improved or optimized in order to survive. Their ranking varies from search engine to search engine and depends on the parameters used when performing a search. How does a search engine ranking come about and how can it be influenced? Search engines process requests fully. They use certain algorithms, which are ultimately also responsible for the ranking, collection, and preparation of results.
There has been increasing awareness not only within the medical profession but also among politicians that marijuana has demonstrable effectiveness in the treatment of a wide range of ailments. Cannabis has been found to reduce the nausea and pain resulting from chemotherapy regimens used in cancer treatment, as well as pressure effects within the eye that are one of the primary symptoms of glaucoma. While these appear to be recent discoveries, Western medicine is, in fact, making a belated rediscovery of an effective medicinal plant used worldwide for thousands of years.
The History of Medical Marijuana
The Chinese were among the first peoples to discover the health benefits of Cannabis Sativa. The Emperor Shen-Nung, in his book on pharmacology written in 2737 B.C., included a complete description of the plant as useful for the treatment of ailments ranging from gout, nausea, and constipation, to absent-mindedness in the elderly. Similar works in Hindu and Egyptian medical libraries also documented the usage of cannabis for various illnesses, as did Greek, Roman and Arabic treatises on herbal medicines in succeeding centuries.
The West Discovers Weed
Western medicine became acquainted with the pharmacological properties of marijuana in the 1830s, with its usage spreading across Europe and eventually to America by 1856. However, by the end of the 19th century, a combination of factors would result in its decline in clinical usage. These included the lack of proper dosage control, the ability to directly inject opium-based and the later synthetic drugs for much faster delivery, and other cultural and political factors that eventually led to the wholesale criminalization of marijuana by the federal government in 1970.
Modern Medical Marijuana
The change in attitudes toward the medical usages of marijuana were initiated by physicians willing to brave criminal sanction by prescribing the drug to relieve pain in cancer and AIDS patients. Since that time, increasing public and professional advocacy has resulted in changes to the laws, and marijuana is now being recognized as a legitimate treatment agent once again.
With the reappearance of medical marijuana, one of the major challenges faced by clinicians and patients is to ensure the delivery of product uncontaminated by various biological and chemical agents that could prove highly toxic.
