Hi Ankur,
I was trying out the PatterMatcher it works for smaller path, but I see that for the longer ones it continues to run forever...
Here's what I am trying: https://gist.github.com/hihellobolke/dd2dc0fcebba485975d1 (The example of 3 share traders transacting in appl shares)
The first edge pattern list (Line 66) works okay, but the second one (Line 76) never return..
Thanks,
Gautam

Then you can make a new graph consisting of the union of the original edge set and the new edges. Let me know if you'd like help with this.
