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.-- This message was sent by Atlassian JIRA (v6.2#6252)
