I tried an experiment running RowSimilarity with 16 docs of short
quotations on a similar subject. It looks to me that using tanimoto the
largest pair-wise distance allowed for the similar docs was 0.4. Though
I asked for 10 similar docs I got 0 to 10. I see this same effect with
larger data sets but haven't seen an obvious cut-off point
I was expecting to be able to make the decision about cut-off distance
myself. In other words I was expecting to always get 20 similar docs
when I asked for 20. It is useful to see what docs are at larger distances.
How is RowSimilarity deciding when to cut-off the returned docs?
