I found the thread:

http://www.openldap.org/lists/openldap-software/200405/msg00022.html

so to answer my own question, I should change nothing because initial 
and final substrings index minimum key length is 2. However, for (*ab*), 
the substring index key length is set in servers/slapd/slap.h. Sorry to 
be a bother, but if this isn't it

#define SLAP_INDEX_SUBSTR_MAXLEN    4

could somebody set me straight? I'll give it a go, otherwise.
