it does not work .
I want all users to be able to do the search to find the information of the new line created

Please give a little more information. What doesn't work?
- Have you entered some data in your field?
- Can you add the custom filter, as recommended before?
- Is Odoo filtering properly your records?

Proces to incorporate a new field for use in the "search" bar, so all users can use it:
From Studio, click on the menú option "Views", then clic on "General views/Search". Drag the field you want to use as a filter and drop it in "Autocompletion fields" box.

(I will add this steps to my answer)
