Anyone that have experience of setting the language in suitescript when running saved searches and loading records to get everything translated and not use the user's language?

you can try to add 'language' to filters (any of desired language in format 'en_US') and 'displaynametranslated' as a column

@Kostiantyn I have tested that but I get problems if I join in other record types. Then I need to add a filter on language for that record too. I also would like to retrieve information from a record.load based on a chosen language.
