There are more than 13 million records in the table. This request is processed in 80 seconds. Which is a very long time. Since ILIKE is used, indexing does not work. How can I optimize my query? Maybe I need to create a FULL TEXT INDEX for all fields?

select *, "user_apps"."id" as "uaId", "messages"."id" as "messageId"
    from "messages" 
    left join "user_apps" on "user_apps"."id" = "messages"."user_app_id" 
    where "user_apps"."unique_id" ilike '%12346789%'
    or "sender" ilike '%12346789%' 
    or "message" ilike '%12346789%' 
    or "receiver" ilike '%12346789%' 
    or "messages"."country" ilike '%12346789%' 
    or CAST(message.id as VARCHAR(255)) ilike '%12346789%' 
    or "sim" ilike '%12346789%' 
    and "type" = 'message'
    order by "messageId" desc 
    limit 51 offset 0
