Dont have time for a big answer, but you are searching in a field called
"contents", and from my quick glance, there is no such field?
As i can see, you have two fields called "resume_name" and "details"
So, you would have to search in the field details. Also remember that
field-names are case-sensitive.
Hope this helps, Aleksander
