Hi, I've managed to nail down a problem with filter overwriting all instances of a variable (as mentioned under different contexts) - here it is in the simplest form (with live uri's so you can see yourself)
# simple query which returns 113 results # live run: http://bit.ly/aVpuNK select * where { u:49991734 t:following ?x1 } # simple query filtered which returns 53 results # live run: http://bit.ly/9sSOLp select * where { u:49991734 t:following ?x1 . ?x1 t:following ?y1 . filter( ?y1 = u:49991734 ) } # problem query, same as above but with optional # *should return* 113 results, 53 with optional ?y1 set to u:49991734 # *actually returns* 113 results with all ?y1 overwritten as u:49991734 # live run: http://bit.ly/d1hP4q select * where { u:49991734 t:following ?x1 . optional { ?x1 t:following ?y1 . filter( ?y1 = u:49991734 ) } } Version is 6.1.0.3127-pthreads as of Feb 16 2010 w/ the last patch you sent me to speed up IN functionality. Many Regards, Nathan
