search word does not work on Pro v2.81

[ad_1]

Hi, I got a Pro Version 2.81

I have a product named like , for example

Pantalla SM-A025F/E025F A02s/F02s 2020 Negro SERVICE PACK No Version EU

when I search by a025f or SM-A025F or A025F , none of them works

if I replace the URI manually from

/?s=SM-A025F&post_type=product&type_aws=true&aws_id=1&aws_filter=1

/?s=SM-A025F&post_type=product

as fall back to default search , then it works

I tried re-index , but seems no good

please help

best regards,
