Abstract: Various embodiments of systems and methods for a document search wrapper are described herein. A database search framework is provided for performing a database search. The database search framework includes a base search wrapper class and an application specific search wrapper class. The base search wrapper class includes common search methods and re-definable search methods. The common search method defines common search logic. The application specific search wrapper class includes the common search method inherited from the base search wrapper class and application specific search methods, created by redefining the re-definable search method. The database search framework may also include a search interface for providing pre-selection or post-filtering logic to the search.

Abstract: A computer system including a database having a database table for storing records including first columns for storing data values, and at least one second column for storing keys identifying records stored in the database. The computer system also including a set of index tables with each having assigned thereto an index table identifier, an arrangement for receiving a query an arrangement for storing a predefined ordered sequence of index table identifiers, and an arrangement for processing the query by checking each one of the index tables for being relevant for the execution of the query, storing the index table identifier for each relevant index table in a query execution table, sorting the query execution table in accordance with the predefined ordered sequence, and executing the query using the index tables identified in the query execution table in the order given by the sorting of the query execution table.

Abstract: The invention relates to a computer system comprising: a database having a database table for storing records comprising data values, the database table having first columns for storing the data values, each one of the first columns being assigned to a data field of a set of predefined data fields, and at least one second column for storing keys, each key identifying one of the records stored in the database, and a set of index tables, each index table being assigned to one of the data fields and having assigned thereto an index table identifier, means for receiving a query, the query specifying the subset of the set of data fields and a search range for each specified data field, means for storing a predefined ordered sequence of index table identifiers, means for processing the query by checking each one of the index tables for being relevant for the execution of the query, one of the index tables being relevant if the one of the index tables is assigned to one of the specified data fields, storing the inde
