DB2 FOR LUW / DB2FORLUW / 970 - DB2

Query using text search will crash instance when text function 
(SCORE, NUMBEROFMATCHES, CONTAINS) are present in a sub-select 
containing an OUTER JOIN or when the input column to the text 
function is produced from the result of an OUTER JOIN operator 
in a sub-select or view. 
 
 
Furthermore this occurs when the text function is used as an 
input to another function or basic predicate where the text 
function result is checked to be greater then a value, for 
example 
 
CONTAINS(...) > 0 
CONTAINS(...) >= ? 
? < CONTAINS(...) 
1 <= CONTAINS(...) 
 
In stack will see functions similar to the following

For the CONTAINS function the workaround to this problem is to 
change the basic predicate so that the result of the text 
function is compared less then a different value. For example 
 
     WHERE 0 < CONTAINS(T1.T1_DATA,'Example') 
 
Instead use the following which will avoid the error. 
 
     WHERE 1 >= CONTAINS(T1.T1_DATA,'Example') 
 
Similar workaround may be possible for the SCORE and 
NUMBEROFMATCHES functions.
