In different tests I found strange behaviour for IDM, and I need to understand how precise is this technology and how to explain this to the customers.
1.I have a 3 pages word document (word 2010) = FullTXT.docx
I delete some text from this document and obtain half page of text in a word file = indexTXT.docx
This file coupled with other files are indexed in an IDM profile that is used in a DLP policy.
As I know from theory, if I will use the FullTXT.docx it will match 100% on the IDM policy.
In my tests I found the match only with 88%.
2. Also on an RA at a client, I found an incident with 100% match between an email and a simple word file, but more words from the IDM indexed file was not found in the email.
How is working the idexing in the IDM technology and how I could explain this behaviours?
Thanks,
Sorin
