Search engines Definition and 12 Threads

A web search engine or Internet search engine is a software system that is designed to carry out web searches. They search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs) The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. Internet content that is not capable of being searched by a web search engine is generally described as the deep web.

    Limitation of the number of search terms in search engines

    Why does Google limit its searches with 32 terms? I think other search engines seems to not limit but adding more terms for some reasons such as filtering does not work, for example in Yahoo. Thank you.

    Could google scholar replace other search engines?

    We have many engines to search the literature, such as sciencedirect and so on. And we also have google scholar to search the whole literature. Is it a good idea to use only google scholar since it looks complete enough? What's your opinion?

    Could Cache Optimization Boost Search Engine Speed by 25%?

    Might a road to significantly faster search engines (25% faster) be via use of a cache of say the 100,000 most frequent search words and phrases utilized, typical for over a year? Might one have perhaps a number of distributive caches for a multitude of different processors and associated memories?
