Hi miguel1258 ,
Apologies for the delay in answering your post.
We wrote a response, but we didn't send it for any reason.
You can search by inventory name by choosing the "Product Name" in the Search dropdown.
FYI, we've found a bug in the search code that will prevent the search from working if your WordPress installation uses a custom database prefix. We fixed it already. The changes will be included in the next ATUM Multi-Inventory version.
Best Regards,
José Andrés
