Merge two Collection Reader

[Wahed Hemati]

Hi,

is it possible to combine two collectionreader in one Pipeline. (e.g. 
SimplePipeline.runPipeline(xmireader, teireader, 
builder.createAggregateDescription()); )

I want to calculate TF-IDF values from two different sources as one 
Collection.

Thanks in advance.
