CREATE INDEX layer_record_nominativo ON production_tlp2020 ((distinct (array array_element for array_element in suffixes(upper((body.nominativo))) end))) WHERE (_type = "record");

select body.nominativo

from production_tlp2020

where ANY array_element IN SUFFIXES(UPPER(body.nominativo)) SATISFIES array_element like '%PIL%' END and _type='record';

where ANY array_element IN SUFFIXES(UPPER(body.nominativo)) SATISFIES array_element like '%PIL%' END and _type='record';

After some time the index keys become as follows and index is not usable.
