Search Logic

The default setting is Or Selected Items. With this setting, clicking Find Next locates all
selected items in turn. If you choose And Selected Items, you can set a logical AND
combination of items to find. Both options allow setting Advanced search features.
Search looks for entities in a trace. When you choose SCSI command AND SSP frame, for
instance, search will return all entities in the trace that are SCSI commands, AND are SSP
frames. Any SCSI commands that are NOT SSP frames, will not, in this case, be returned.
If you choose OR, search will return all entities that are SCSI commands as well as all SSP
frames.
The AND operator is only applicable for some cases, such as:
For example, when you choose a SCSI command AND a tag = 0x1, you will get all entities
on a trace that are SCSI commands that have tags equal to "0x1" in that SCSI command.
As a general rule, it is not possible to apply AND on two packet types (frames, commands,
primitives, training sequences or bus conditions). It only works when you apply AND on
one packet type with other items such as source/Destination Addresses, TAG, Task
attribute.
