ECKS-PS algorithm: searching in encrypted data; bilinear maps
I have found an encryption algorithm named ECKS-PS (published in a paper named 'efficient conjunctive keyword search on encrypted data storage system') that allows an user to search in encrypted data. All the steps are described here: img210.imageshack.u s/img210/4644/eckps.png
And I have written them a little bit more clear here: img801.imageshack.u s/img801/3373/stepsecksps.jpg
I have tried to find a calculation example of finding two words multiple times (see calculations: img4.imageshack.u s/img4/474/firstpagecalculations.jpg and img805.imageshack.u s/img805/8712/secondpagecalculations.jpg) but I never get a match.
Can anybody tell me what I am doing wrong and/or provide me with an example where you get a match (based on the ECKS-PS algorithm). I know there may be other algorithms to search in encrypted data but I would like to know how to do it with this algorithm.
Thanks in advance
P.S. Sorry about the 'urls' but I needed the images to explain

You wrote that you found this algorithm -- where?
I think it will help if you can cite a reference -- a paper, or a website -- so we can see the definition of this algorithm.

Thank you for your answer.
The source is an published paper that I found in my school library (In Proceeding of European PKI Workshop: Theory and Practice (EuroPKI) 2006 , LNCS Vol. 4043, pp. 184-196, Springer-verlag, 2006 (SCIE). The definition of the algorithm can be found in my first link (img210.imageshack.us/img210/4644/eckps.png)
