Using Our Search Feature
Natural Language Search Operators
You can use the special search operators and, or, and not when searching. Without these operators our search engine will assume you're and'ing the words together. Search terms and the special operators are not case sensitive so the following four searches will all return the same results :
The not operator will find documents without a specified search term. So the following search will find all documents without the term "water" :
The or operator will find documents that include either of two or more search terms. So the following search will find all documents containing either the words "water" or "air" :
These natural language operators can be combined so that the following search will find all documents containing either of the terms "water" or "air", but not the word "gas"
Note : To search for the actual words and, or and not, place them in a double quotes:
Search Wildcard
The search wildcard character * means "match zero or more characters." and may be used at the end of a word to broaden your search.
For example the following search will only retrieve documents which contain the given word:
However, the following search will find all documents containing "electric", "electricicity" and "electrical"
