Different result per language

Problem/Motivation

When i search for code PMD05663 in different language i get different result.

If i search PMD05663 in English i get only one result.

if i search PMD05663 in Italian i get PMD05663 as first result of many others.

Why different behavior?

Steps to reproduce

Add italian language
Create entity
Add 2 field text not transatable (field_one and field_two)
Create solr index
Add field_one and field_two
Setup fulltext "edgestring"
Create a view with fulltext search filter
