Major Since NXS-2212, the default search form is built with incorrect predicates for the tags and path field.
<predicate parameter="dc:path" operator="STARTSWITH">
<field schema="default_search" name="ecm_path"/>
</predicate>
<predicate parameter="dc:tag" operator="IN">
<field schema="default_search" name="ecm_tags"/>
</predicate>
dc:path and dc:tag does not exist and must be replaced by ecm:path and ecm:tag
