Different behavior in front and back office for accent for the search

[lydipi]

We notice that in back office, if we do a research with accent (à, é, è, etc.) we can’t find a document.
For example we can find it if accent is in the query:
https://catalogue.library.cern/backoffice/acquisition/orders?q=%22El%20bos%C3%B3n%20de%20Higgs%20no%20te%20va%20a%20hacer%20la%20cama%22&l=list&order=asc&p=1&s=15&sort=bestmatch

But if we don’t put the accent, we have no result: https://catalogue.library.cern/backoffice/acquisition/orders?q=%22El%20boson%20de%20Higgs%20no%20te%20va%20a%20hacer%20la%20cama%22&l=list&order=asc&p=1&s=15&sort=bestmatch

In front office, it works. Would it be possible to ignore accent everywhere in CLC, front and back?
