Diagnosis
You entered a character string as search criteria, which contains blankcharacters, without the phrase indicator being set. This is notallowed.
There are two different query possibilities:

• Search criteria enter the query as the only terms to be linked.


• Search criteria enter the query as a character string (= phrase); this
is determined by the phrase indicator. If the indicator is set, thenword chains, which are separated with blank characters, are used forthe query. In addition, uppercase and lowercase is then also taken intoaccount.

Procedure
Either correct the entry for the desired search criterion, by makingsure that no blank characters occur within the search criterion, or setthe phrase indicator so that blank characters can be used.
