Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Quiesce and Idle of a System
This mechanism is used to quiesce and idle a system with a system
controller that connects with all other elements of the system. The mechanism
ensures that no data transfers are taking place.
"Quiesce" is a function that assures that no data transfer is taking place in the
system. This state is required for the case where clocks are to be stopped, for
example, error recovery where clocks are stopped and data is scanned, and
normal clock-stop for displaying or altering the system. If clocks are arbitrarily
stopped, data transfers may or may not be complete, resulting in questionable
data integrity and/or additional error conditions.
Quiesce requires the ability to complete storage operations that are
underway, but not accept any new operations; those which are waiting remain
In a system with a System Controller (SC), e priority mechanism (Q Array)
can hold storage requests that are outstanding, waiting for a storage module to
Quiesce (a) prevents all external service requests to the System Controller
from competing on the SC's priority network, (b) allows, all operations underway
to continue to their normal completion, and (c) allows commands waiting in the
queue to be executed. Those commands that cannot be executed because they
are waiting for castout or invalidate directory entry will exit when normal
operation resumes and the conditions are satisfied.
