I have a very long search, with extracted fields, regex and calculated fields, but I don't think that the problem are the fields because the correct result is the one obtained in Fast Mode.
Everyway, running the same search on a less time period (less events), I have the same results for Fast, Smart and Detailed Search Mode.
In addition, I have my events in two indexes: events from ArcSight in "GP2-arcsight" index and events received directly from host (the same that before sent events to ArcSight) in "GP2" index.
The first one is divided in 167 buckets and the second one in 4 buckets.
Running the same search on the second index (with about the same number of events) I have the same results for Fast, Smart and Detailed Search Mode.
For these reasons I think that the problem could be the number of buckets that reaches the limit of 300, but I wasn't be able to find where to set this parameter.
Thanks.
Bye.
Giuseppe
