Bug 7886 - C4/ShelfBrowser slow SQL performance
ShelfBrowser uses two SQL queries with syntax
WHERE ((cn_sort = ? AND itemnumber < ?) OR cn_sort < ?)
AND homebranch = ? AND location = ? AND ccode = ?
homebranch already has index, and adding indexes on ccode and location
improves performance by 30% for each query since MySQL is able to use
index_merge intersect(items_ccode,homebranch,items_location)
