Database search engine

Database search engine
There are several categories of search engine software: Web search or full-text search (example: Lucene), database or structured data search (example: Dieselpoint), and mixed or enterprise search (example: Google Search Appliance). The largest web search engines such as Google and Yahoo! utilize tens or hundreds of thousands of computers to process billions of web pages and return results for thousands of searches per second. High volume of queries and text processing requires the software to run in highly distributed environment with high degree of redundancy. Modern search engines have the following main components: Searching for text-based content in databases or other structured data formats (XML, CSV, etc.) presents some special challenges and opportunities which a number of specialized search engines resolve. Database search engines were initially (and still usually are) included with major database software products. See also[edit] External links[edit]

99 Resources to Research & Mine the Invisible Web College researchers often need more than Google and Wikipedia to get the job done. To find what you're looking for, it may be necessary to tap into the invisible web, the sites that don't get indexed by broad search engines. The following resources were designed to help you do just that, offering specialized search engines, directories, and more places to find the complex and obscure. Meta-Search Engines-The Library "Smarter" meta-searcher technology includes clustering and linguistic analysis that attempts to show you themes within results, and some fancy textual analysis and display that can help you dig deeply into a set of results. However, neither of these technologies is any better than the quality of the search engine databases they obtain results from. Few meta-searchers allow you to delve into the largest, most useful search engine databases. They tend to return results from smaller and/or free search engines and miscellaneous free directories, often small and highly commercial. Although we respect the potential of textual analysis and clustering technologies, we recommend directly searching individual search engines to get the most precise results, and using meta-searchers if you want to explore more broadly. The meta-search tools listed here are "use at your own risk."

YOU CAN BUILD YOUR OWN ADD~ON GREENHOUSE It's a snap to design and build your own add-on greenhouse from low-cost new and salvaged materials. You Can Build Your Own Add-On Greenhouse For decades, the height of gardening and "food self-sufficiency" luxury has been the private greenhouse. Unfortunately — or, perhaps, foolishly — too many of us have traditionally regarded a family greenly greenhouse as just that . . . a luxury that "maybe" we'll be able to afford "someday". Internationally recognized greenhouse gardening authority Jack Kramer doesn't agree with that line of thought at all. "Far more people than realize it can have a greenhouse right now," says Jack. Deep Web Research 2012 Bots, Blogs and News Aggregators ( is a keynote presentation that I have been delivering over the last several years, and much of my information comes from the extensive research that I have completed over the years into the "invisible" or what I like to call the "deep" web. The Deep Web covers somewhere in the vicinity of 1 trillion plus pages of information located through the world wide web in various files and formats that the current search engines on the Internet either cannot find or have difficulty accessing. The current search engines find hundreds of billions of pages at the present time of this writing. In the last several years, some of the more comprehensive search engines have written algorithms to search the deeper portions of the world wide web by attempting to find files such as .pdf, .doc, .xls, ppt, .ps. and others. This Deep Web Research 2012 report and guide is divided into the following sections:
