摘要：
An integrated search engine device contains a pipelined arrangement of a plurality of search and tree maintenance sub-engines therein. This pipelined arrangement of sub-engines includes a hierarchical memory, which is configured to store a plurality of databases of search prefixes. These databases are arranged as a corresponding plurality of multi-way trees that span multiple levels of the hierarchical memory. The plurality of search and tree maintenance sub-engines are configured to respond to a database flush command by redesignating active nodes of a selected database within the hierarchical memory as free nodes using downstream and upstream communications between the plurality of search and tree maintenance sub-engines.
