   Having difficulties with the Find Similar Defect feature. Have not been able to predict matches, and getting the same match several times is not consistent.

   What I am looking for is an explanation of how the search is performed. Have spoken with Mercury Customer Support; "Application Engineer" did not seem confident in his answer. Stated that there had had to be at least a 36% match between the summary fields in order for TD to consider it a match. Also stated that a summary that had more words (longer) had a better chance than a short summary. (Even if the short summaries are different only by 3 characters???)

   If I could get an explanation on what the logic was, I could perform more accurate, faster searches. Any ideas?

   This topic has been previously discussed, but there haven't been any updates since October 2001

   As best I can tell, it searches words within the subject field.

   And not well.

   It's a hit or miss kinda thing right now, something Merc really needs to improve upon.

   Here is the explanation that was sent to me from Mercury - they say it was in the Knowledge Database (which I know I checked, but didn't find a anything that was "similar" to my question - that search function must be similar to the one used in Test Director)

   The Defects Manager matches defects based on the percentage of detected similarity between the selected defect and the rest of the defects in the given database.

   For a selected defect, the Defects Manager creates lists of keywords from both the Description and Summary fields. Words in these fields are matched against other defects.

   The minimum threshold for defects to be similar is about 40%. So if the list of keywords for a selected defect's Description AND Summary fields match at least 40% of another defect's Description AND Summary fields, then it will be found as similar. This is why you can select one defect and find similar defects, and then select one of the similar defects and not find the originally selected defect.

   So if you have two defects with the same exact Summary data, but one defect has no Description field data and the other has a long description, making the similar threshold under 40%, the defects will not be found as similar.

   Hope this is helpful to other users. We are now having more success with the "Finding Similar Defects" function.

   Not sure if this helps but you can use a expression like *text* to find a specific word in the defect summary.
