Site search criteria not homogeneous

[nicolatron]

When searching for a site in "Cabel Plant"->"Sites"->Site Search
It seems to search at least in site.name, site.number, site.aliases fields.
When searching in modal boxes, for example in a network and go to the Tab "Sites"->[add] (example link /netdot/management/edit.html?table=SiteSubnet&subnet=3)
There is a text box and next to it a List button, that should load matched sites in a combobox element.
It seems to search at least in site.name, site.aliases but site.number is omitted.
