How to build Siebel Workflow Expression?

I remember my days when i started with Siebel, I just couldn't get the syntax of workflow expression correct. I still see newbies of siebel struggling to get it right the first time. In this post I would try to make the basic rules of workflow expressions as simple as possible.

Basic Rules of Siebel Workflow Expression are :

1. Siebel Workflow takes String as input.
2. + (plus) is the concatenation operator.
3.  Process properties can be referred using & operator like this > [&Object Id] 
4.  Don't worry about spaces in process property names, they are allowed.

Let's take an simple example where we want to build the expression to search for records with Contact Id specified in Object Id the search spec would be:

if Object id contains : 1-12345 then expression will be evaluated as :

Did I say its a H.U.G ?
