3.4.7.2 nsSubStrEnd
By default, for a search to be indexed, the search string must be at least three characters long, without counting any wildcard characters. For example, the string abc would be an indexed search while ab* would not be. Indexed searches are significantly faster than unindexed searches, so changing the minimum length of the search key is helpful to increase the number of indexed searches.
This substring length can be edited based on the position of any wildcard characters. The nsSubStrEnd attribute sets the required number of characters for an indexed search for the end of a search string, after the wildcard. For example:
*xyz
If the value of this attribute is changed, then the index must be regenerated using the db2index command.

By default, for a search to be indexed, the search string must be at least three characters long, without counting any wildcard characters. For example, the string abc would be an indexed search while ab* would not be. Indexed searches are significantly faster than unindexed searches, so changing the minimum length of the search key is helpful to increase the number of indexed searches.
This substring length can be edited based on the position of any wildcard characters. The nsSubStrMiddle attribute sets the required number of characters for an indexed search where a wildcard is used in the middle of a search string. For example:
ab*z
