[Zope] Why Plone catalog indexes file added through "Zope" and "Plone" in different ways?

[vaibhav uprety]

Hi,

I am stuck in a very peculiar situation. 

I have added some files through the ZMI's "ADD Menu"
and some files through "PLONE". 
I want to make all of these files searchable through
the search button in plone.
However i found that in the plone catalog
(portal_catalog) indexing of the files that are added
through the ZMI is different from that of the files
added through plone. 
For example,I uploaded a file providing a "title" and
"id" using Zope Management interface but found the
"title" of the file with some other value in the
portal catalog.
------------------------------------------------
  Title  Portal  (this value is wrong)
  Type   Plone Site  
  id     mysql blob  (This is correct)
------------------------------------------------

However when i added a "file" through Plone, the
catalog showed different values for file
--------------------------------------------------
  Title  mysql blob  (correct in this case)
  Type  File  
  id  PhotoTransfer1.java (this is the file i
uploaded) 
------------------------------------------------------

Is the way in which files are cataloged different?
Or am i doing something wrong.
I need a standard way to "catalog files" so that files
are displayed in the search result irrespective of
their adding method.

Please help me to correct this problem !!
