Abstract: Described is a method for generating a parametric search statement for finding a target document. The parametric search statement is generated in the text boxes of a search bar. A user action is performed in the text box. An in-place context menu having menu items responsive to the user action are displayed near the location of the user action. Each menu item includes at least one of an attribute of the target document, a comparison operator and a value. One of the menu items is selected from the in-place context menu based on a known characteristic of the target document. Parametric search statements are easily generated using the method without the need to access numerous dialogs boxes or to enter significant text.

Abstract: System control of compression and decompression of data based upon system aging parameters, such that compressed data becomes a system managed resource with a distinct place in the system storage hierarchy. Processor registers are backed by cache, which is backed by main storage, which is backed by decompressed disk storage, which is backed by compressed disk storage then tape, and so forth. Data is moved from decompressed to compressed form and migrated through the storage hierarchy under system control according to a data life cycle based on system aging parameters or, optionally, on demand: data is initially created and stored; the data is compressed at a later time under system control; when the data is accessed, it is decompressed on demand by segment; at some later time, the data is again compressed under system control until next reference. Large data objects are segmented and compression is applied to more infrequently used data.

Abstract: A hierarchical cache system comprises first and second pluralities of data caches and first and second respective higher level caches. The first higher level cache is coupled to the first plurality of caches and stores data of the first plurality of caches. The second higher level cache is coupled to the second plurality of caches and stores data of the second plurality of caches. First and second storage controllers access first and second respective address ranges from a main memory and the higher level cache subsystems. The first higher level cache responds to a request for data not contained in the first higher level cache by determining which of the address ranges encompasses the requested data and forwarding the request to the storage controller which can access the determined address range.
