Ted/Gokhan,
>From the recent thread it seems like Gokhan has a great start on this, let me know if
I can help with integration tests or docs.

> It should be possible to view a Lucene index as a matrix.  This would
> require that we standardize on a way to convert documents to rows.  There
> are many choices, the discussion of which should be deferred to the actual
> work on the project, but there are a few obvious constraints:
> a) it should be possible to get the same result as dumping the term vectors
> for each document each to a line and converting that result using standard
> Mahout methods.
> b) numeric fields ought to work somehow.
> c) if there are multiple text fields that ought to work sensibly as well.
>  Two options include dumping multiple matrices or to convert the fields
> into a single row of a single matrix.
> d) it should be possible to refer back from a row of the matrix to find the
> correct document.  THis might be because we remember the Lucene doc number
> or because a field is named as holding a unique id.
> e) named vectors and matrices should be used if plausible.
