The search <#CURRENTSEARCHTERM> is invalid.

Note that the search might be invalid because certain words you entered are very common and may have been ignored, causing your search expression to have two operators next to each other or similar. In this search the following words (if any) have been ignored:-

Ignored Words: <#IGNOREDWORDS>

Searching rules.

Searches can be constructed using the the word(s) you want to search for and the operators AND OR XOR NOT and brackets ( ). The operators can be in upper or lower case.

Items in brackets are evaluated first in order to reduce such items to a single result, then all items are evaluated in left to right order. All operators are of equal precedence.

If you use brackets to change the order of evaluation they must balance (i.e. there must be as many left brackets as right brackets).

Words which are not separated by an operator are assumed to be separated by AND.

For example, the search -

A and (B or (C and not D))

would first find pages that contained the C but not D, then find those pages that contain the result of that search or contained B and finally determine those pages that contain the result of that search and also contain A.
