We have a Windows Server 2008 R2 SP1 server with the File Services role and the Windows Search service installed. We do not have the Indexing service installed. There is a piece of software that process PDF's and spits out a .img file into a specific folder that contains plain text. Our users need to search for a specific string within these files - '9999' to be exact.  Anyway, we have noticed some inconsistencies as it does not always file the '9999' string.  As a test, I put 2 .img files that I know contain this string in a sub folder.  The search only found the string in 1 of the 2 files.  However, in the file it did not find this sting in I can search for any other piece of information and it finds it.

Under Index Options in the Control Panel I have this folder set to index.  I have also verified the .img extension is a file type to index.  If I look at the properties of that file the option 'Allow this file to have its contents indexed...' is checked as well.

Any reason why the Search service is only finding this string in some of the files and not all of them?  Or why it could search for other information in the file and not this string?  Any help would be greatly appreciated.

Hi,

The '9999' string is a "words" or a substring? If it is a substring, Windows Search Service will miss results.

There is a similar thread, please go through it to help troubleshoot this issue:

Regards,

It is a "word."  The data is comma separated inside the file.  Something like name,date,account,9999,etc,etc,etc.  For the files it doesn't find 9999 in I can search for any other content within those files and it finds its.  All of the content is formatted the same within each file.  Again, if I search for 9999 within the folder I do get results I just don't get all of them.

Any other ideas?

Hi, 

Can you provide a text file for testing purpose? In the meantime, try to index *9999 to see if it can get right result.
