Advanced search
The text search engine allows queries to be
formed from arbitrary Boolean expressions containing the keywords AND, OR,
and NOT, and grouped with parentheses. For example:
| body language |
finds pages containing 'body' or
'language' |
| body or language |
same as above |
| body and language |
finds pages containing both 'body'
and 'language' |
| body and not language |
finds pages containing 'body' but
not 'language' |
