How to Search

• For tips on entering search arguments, you should look at the hints of search engines, for example, on Google.
• However, a general search approach is to try how many search engines push when to stop the search.
• It isn’t easy to generalize, but here are a few helpful tips to help you find it.
• If you know a specialized search engine, like on the TechTarget pages, that fits a topic (e.g., enterprise software or networking), you save time using the site’s search engine.
  If there isn’t a specialized search engine, try Google or Bing. Sometimes you can find a matching result or two, which is often enough.
• If Google is not enough, try other search engines and their results. Depending on how important the search is, the first 20 entries are usually sufficient.
• For an efficient search, you can use a metasearch engine that uses several search engines simultaneously and searches their indices.
• If you haven’t found the correct result at this point, you should use a topic directory approach.
• You should look at Google or the structured topic categories of other search engines and see if you can narrow down a type in which the term or phrase is likely to be found.
• If nothing else is possible, you can come up with ideas for new search phrases.
• You can also search Usenet newsgroups if you deem it necessary.
• While searching, keep thinking about the search arguments. Which new approaches can be uses? What are related topics for search?
• Finally, consider whether the topic is so new that not much is available about it yet.
• If so, one may need to find the latest publications, research institutes, or companies engaged in research or development related to the subject.
