Hi David, This hack works for my example - a scenario to find SetA AND SetB values.
How to get a NOT dataset for facets? e.g. SetA = 25 (13 only A, 12 common with B) SetB = 27 (15 only B, 12 common with A) SetA intersect setB = 12 (common) (using hack) SetA union (or) setB = 13 + 15 + 12 = 40 (using usual facet) How to get values that are in SetA but NOT in Set B = 13 (only A)? Thanks, Mahesh Kulkarni. ---------- Forwarded message ---------- From: David Huynh <dfhu...@alum.mit.edu> Date: Mar 18 2009, 1:26 pm Subject: "AND" between facet values To: SIMILE Widgets Luigi Spagnolo wrote: >> It's a hack, but you can do it by making two facets on the same >> property.

Hi Luigi, Short answer is, no, the listfacetdoesn't support that, yet. The challenge isn't so much in the algorithms, but in the UI. For one thing, the choice counts will be different and harder to understand in the AND case.
