In big databases querying on the EAN can take a while, it would be nice to have
an index on this column as we have on other columns with standard numbers in
this table already:

 196   PRIMARY KEY  (`biblioitemnumber`),
 197   KEY `bibinoidx` (`biblioitemnumber`),
 198   KEY `bibnoidx` (`biblionumber`),
 199   KEY `itemtype_idx` (`itemtype`),
 200   KEY `isbn` (`isbn`(255)),
 201   KEY `issn` (`issn`(255)),
 202   KEY `publishercode` (`publishercode`),
