Natural Language searches for the phrase or words entered as a "free text phrase" and will return posts containing near matches to the phrase first then posts containing the individual words etc. It is the recommended search method.

Boolean Search allows you to use advanced boolean search operators to find, exclude, add or remove weight from specific words or phrases. For example: +assessment -harborne
Would return posts containing the word assessment which do not also contain the word harborne.

Please note all searches will automatically exclude common words found in a majority of posts, very short words and language operators.
