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]

TOP 10 IMPOSSIBLE INVENTIONS THAT WORK « Revolutionizing Awareness Searl Effects Generator by Jeane Manning When Leonardo da Vinci sketched out an impossible invention, fifteenth-century scholars probably put him down. 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. 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:

SmartThings: Make Your World Smarter by SmartThings Extra SmartThings for all! See Update 16 for details. SmartThings makes it easy to connect the things in your physical world to the Internet. 100 Useful Tips and Tools to Research the Deep Web By Alisa Miller Experts say that typical search engines like Yahoo! and Google only pick up about 1% of the information available on the Internet. The rest of that information is considered to be hidden in the deep web, also referred to as the invisible web. So how can you find all the rest of this information? This list offers 100 tips and tools to help you get the most out of your Internet searches.

New M-Block Mini Robots Can Self-Assemble, Jump And Climb A new square mini robot has been created called the M-Block that is capable of self assembly, jumping and climbing. The new move out is fitted with a flywheel and can reach speeds of up to 20,000 revolutions per minute allowing it to create its own angular momentum. To help the M-Block move from one location to another it is also fitted with magnets on each corner as well as its flat faces, allowing modules within the robot to change location. Watch the video after the jump to learn more about these unique and fascinating M-Block robots. The M-Block robots are cubes with no external moving parts and have been created by Roboticists at the Massachusetts Institute of Technology. Daniela Rus, a professor of electrical engineering and computer science and director of MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) explains:

13 Alternative Search Engines That Find What Google Can’t Google has become the standard search engine of virtually every web-goer on the internet today. In fact “to Google” is pretty much synonymous with “to search”. But that certainly doesn’t mean that other search engines can’t do a decent, if not better, job and this list has been compiled for just this reason. So check out this catalog of awesome alternative search engines that are certain to help you search faster and more efficiently on that World Wide Web. Meet The Tacit Project.

Read These Seven Books, and You’ll be a Better Writer Donald Miller I used to play golf but I wasn’t very good. I rented a DVD, though, that taught me a better way to swing, and after watching it a few times and spending an hour or so practicing, I knocked ten strokes off my game. I can’t believe how much time I wasted when a simple DVD saved me years of frustration. I’d say something similar is true in my writing career. If you read these books, your writing will improve to the point people who read your work will begin to comment on how well you write.

Blood Pressure Monitor Loses Cuff The Nihon University has come up with a spanking new kind of blood pressure meter which is capable of measuring one’s blood pressure simply by touching it with a finger. First displayed at Medica 2012 in Dusseldorf, Germany, this particular blood pressure monitor will measure your blood pressure sans the traditional cuff, meaning it is a whole lot easier to deliver readings of blood pressures of babies and elderly people. All it requires is for one to touch a button-shaped small area on the meter, where embedded LEDs and photo transistors in the area will get to work – the former emits light that is then reflected on a finger, where the photo transistors will take over from there and detect whatever reflected light.

30 Specialist (and Super Smart) Search Engines Google is widely (and rightly) recognised as the mother of all search engines. But, if you need to drill down your searches by more specific details, do you trust Google to give you what you need every single time? Here’s a collection of 3o vertical search engines which you should have up your sleeve when you need some specialist power. Flights / Travel Toolkit Transforms Whiteboard Sketches Into Functioning Apps [Video How would you like to turn your sketches into functioning prototypes? AppSeed lets you do just that. The app enables designers and developers to create prototypes faster and more easily by directly transmitting drawings from paper to phone; it uses computer vision to crop and isolate each image. Once the images are isolated, users can then alter or designate specific functions to it. Looking to find an easier way for developers, AppSeed allows for simple manipulation and modification of digitized sketches.
