(followup from bug 585094 comment 6) STR 1 Search all messages (global search) with > 400 matching messages (according to bug 585094, comment 6) alternatively, 2 Search all messages (global search) for messages that have duplicates in some other folder etc. Actual result both 1) and 2) TB makes no indication whatsoever that the number of results given does not reflect the actual total number of matches Exepected need functionality and UI to indicate that number of results given is not the actual total number of matches

STR/Actual results: For global searches with > 400 actually existing results, we usually stop at 400 and claim that there are 400 matches (on fancy faceted results). Combining step 1 and 2 makes this even more misleading because we first limit the number of results to 400, and *after that* take out the dupes, which results in seemingly precise result counts like 395 (as I just tried on a folder that had > 5000 matches). In the case of dupes (even for < 400 matches), we simply ignore the number of duplicate messages, e.g. in Sent, Archive or Backup folders, when calculating the result count.
