Clearify sliding windows behaviour regarding literal and non-literal values
---------------------------------------------------------------------------

                 Key: JBRULES-3312
                 URL: https://issues.jboss.org/browse/JBRULES-3312
             Project: Drools
          Issue Type: Patch
      Security Level: Public (Everyone can see)
    Affects Versions: 5.3.0.Final
            Reporter: Markus Merder
            Assignee: Mark Proctor
            Priority: Optional


Regarding JBRULES-2823: I don't know how to supply a patch for the fusion user guide, so I'll just type here:
To the orginal: 
"For instance, if the user wants to consider only the last 10 IBM Stock Ticks, independent of how old they are, the pattern would look like this:

StockTick( company == "IBM" ) over window:length( 10 )

As you can see, the pattern is similar to the one presented in the previous section, but instead of using window:time to define the sliding window, it uses window:length."

you should append the following to clearify:
"Be aware that only literal conditions are applied before the window is applied. So the following rule would consider only the IBM stock ticks WITHIN ALL last 10 stock ticks:

@company : Company(name == "IBM")
StockTick( company == @company ) over window:length( 10 )
"
