A product name with a spelling mistake or a wrong plural? It can cause needless scares for your colleagues.
Never forget that data is shared in Odoo and that the ERP does not correct typos!
As a salesperson, I want to find a contact in my CRM so I can follow up.
This contact is Flottille
In my contacts list, in the search box: 
The software does not find Flotille, because the word flottille is correctly spelled with 2 t's and 2 l's
Odoo offers me several search fields, the most common being "in Name"
The simplest approach is to search on part of the name, as in most software that allows this kind of search.
The system then filters all contacts (companies and people) that contain flot in their name.
And there you go, you just have to know it :)
