there is a group by text_topic_text_medium_id_text_medium!
the query should count the files that contains specific bi-gram in each medium.
from inside out:
select files ids that contain the bi-gram
select meta data id for the selected files
count the files in each medium
flag1..5 is an integer flags I need them to know if the file processed or not.
I just noticed the redundancy, thanks.
and about auto increment without it I got error in the code if I insert a new record
