The key to being a savvy online searcher is to use common search techniques that you can apply to almost any database, including article databases, online catalogs and even commercial search engines. This is important because searching library databases is a bit different from searching Google.
The use of AND
AND is used to tell the database that you want to retrieve documents or items which contain both (or all) of the keywords you specify. It is used to connect unrelated terms or concepts. A search using AND with these keywords would look like this: Aspergers and Education
The use of OR
OR is used to communicate to the database that you want to retrieve documents which contain one, or the other, or all of the terms that you specify. It is used to connect related or synonymous terms and is a very powerful tool in keyword searching. OR allows you to ask the database to retrieve all these variants. For example, an OR search: Pervasive Developmental Disorders or Autism Spectrum Disorders
The use of NOT
NOT is used to communicate to the database that you do not want the items it retrieves to contain certain terms that you specify; that is, it excludes results. Such as Autism not Aspergers. This will give you search results about autism but not aspergers.
This is a technique that broadens your search to include various word endings and spellings.
- To use truncation, enter the root of a word and put the truncation symbol at the end.
- The database will return results that include any ending of that root word.
