Carlo Accorsi commented on DIRSERVER-1854:
------------------------------------------

I will send a complete configuration along with a code example but this is what 
seems to cause the issue. 

After a modification (containing multiple mods on indexed attributes) at least 
one of the indexes gets corrupted. 
After the modification, a search for displayName=* does not include the entry 
that's just be modified. 
The cn=* still returns the the entry that's just been modified  However if i 
modify second entry, with a single modification to the displayName
this also disappears from the index. 

Here is the code snip. 
                
                        LdapConnection  connection = 
obj.setupConnection("localhost",10389,"uid=admin,ou=system","secret");
                        // search for (displayName=*) here returns 3 values
        
                        Entry entry = 
connection.lookup("uid=1370924523315,ou=users,ou=int,o=cpro");
                        Dn dn = entry.getDn();

                        Attribute atCommonNameNew = new 
DefaultAttribute("cn",new String[]{"Test User XYZ"}); // value changed
                        Attribute atDisplayNameNew = new 
DefaultAttribute("displayName",new String[]{"Test User XYZ"}); // value changed
                        
                        
                        Modification[] mods = new Modification[2];
                        
                        mods[0] = new DefaultModification( 
ModificationOperation.REPLACE_ATTRIBUTE, atCommonNameNew);
                        mods[1] = new DefaultModification( 
ModificationOperation.REPLACE_ATTRIBUTE, atDisplayNameNew);
                        
                        connection.modify(dn, mods);
                        // search for (displayName=*) here returns 2 values

>             Project: Directory ApacheDS
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 2.0.0-M12

>            Reporter: Carlo Accorsi

> We have several attributes indexed on a custom partition. The first time the 
> entry is created and saved, the attribute is searchable with a wildcard. For 
> example, if there are two entries with the following CN's: 
> cn: User One
> cn: User Two
> the search cursor for (cn=*) will return two entries. If the cn on one of the 
> entries is changed with a replace modification, (cn=*) will not include the 
> entry in a result.  This behavior is observed with other indexed attributes 
> as well.
