Search EnginesThose of us who work in IT industry know that key to success is knowledge. Knowledge of your chosen market, of your competitors, new software, new hardware and a million other things that you need to know.
Granted, it’s not an easy task. It often takes dedicated ‘geeks’ continually surfing Net for necessary information day in, day out, to filter through masses of information overload that is commonplace on Net today. But there are certain ‘methods’ that might make it a bit easier and more efficient.
Most users of Internet are familiar with ‘Search Engines’ but few understand how they actually work and although it isn’t necessary to understand actual algorithms used for individual engines it’s important to have an idea of type and quality of results that get shown.
The main types of engines are generic search engines such as Google and All The Web, next are Directories such as Yahoo and finally there are Meta Search engines such as IXQuick and Metor. Although there are others such as PPC’s and Mete-meta search engines (All in one) I won’t list them all as it may confuse issue.
These engines provide results in different ways and, if you can understand them, will enable you to find more information on any particular topic than would normally be available to you if you were to use only one or two engines.
Firstly, generic search engines use an automated searching program (spider) to try and locate any site that matches query that you entered into its search box. It then lists them according to its own idea of what it believes is most relevant to you. The directories, however, have humans to sort out different sites into different sections and hopefully weed out sites that would not be appropriate to your request. These are a bit more limiting but often give quality information. Lastly we have Meta search engines, these utilise services of a multitude of different search engines to search simultaneously for sites that match your query. Again, they then sort out sites according to what they believe might be most relevant to you. The biggest use of these is to find leads for a subject you are not familiar with.
Ok, that’s basics sorted out.
Advanced search tools
Many engines have advanced search features that use a mixture of Boolean search tools and restrictive results that can give a more precise return on your query. These normally include instructions such as:
