| The knowledge base is the collection of posts and comments that formed the old forum, this search will extract any posts that match the selection criteria |
| Search criteria | |
|
| The search criteria may be a simple search such as a single word, any post that includes this word will be retrieved. |
| More complex search criteria may be defined: |
| 2 or more words separate by a space are treated as AND os a b c is a AND b AND c and only post that contain all three words will be retrieved. |
| If 2 or more words are surrounded by quotes, they are treated as a single item, so "a b" c will search for a b AND c, unlike the example above, a post will only be retieved if a and b are separated by a space and c exists somewhere in the text. |
| Instead of the default AND, OR may be used; a b OR c will find posts that include both a and b or just c |
| The search criteria is evaluated from left to right so in the above example a search is first made for poststhat include both a and b, if this test fails, posts that contain c will be retrieved. |
| To alter the order of precedence, brackets may be used; without brackets a OR b AND c would look for a and c or b and c. However a OR (b AND c) would look for text a or both b and c |
