+Hello, \r
+\r
+I'm finding that when I use the --limit option with the output=files and\r
+offset=N that the returned list of files is of variable length.\r
+\r
+For instance when:\r
+\r
+notmuch search --output=files --offset=6 --limit=2 steve\r
+\r
+it returns\r
+\r
+/var/spool/mail/virtual/archive/sl/.Sent/cur/1335243985.M765351P23366V000000\r
+0000000801I0000000000820E9C_5.archive,S=275069:2,S\r
+/var/spool/mail/virtual/archive/sl/.Sent/cur/1335243986.M749883P23366V000000\r
+0000000801I0000000000820E9D_6.archive,S=275069:2,S\r
+/var/spool/mail/virtual/archive/sl/.Sent/cur/1335243987.M926961P23366V000000\r
+0000000801I0000000000820EA0_9.archive,S=111888:2,S\r
+/var/spool/mail/virtual/archive/sl/.Sent/cur/1335243988.M718230P23366V000000\r
+0000000801I0000000000820EA1_10.archive,S=111888:2,S\r
+\r
+Which is two more results than required. If I choose different offset values\r
+then the number of returned results will vary too. \r
+\r
+If I issue:\r
+\r
+notmuch search --offset=6 --limit=2 steve\r
+\r
+It returns two results as expected, if I change the output type to anything\r
+other than files (summary/threads/messages/tags) then the correctly limited\r
+list is returned. So it only seems to happen with the files output type.\r
+Both json and text format types exhibit the same behaviour.\r
+\r
+Am I using this correctly ? I expect only two results to be returned but\r
+being new to notmuch gives me doubts that what I am doing may be incorrect.\r
+\r
+My apologies if the mailing list is not the place for this sort of report,\r
+please direct me to a more appropriate place.\r
+\r
+Many Thanks\r
+Jake\r
