Abstract
A method performs a lookup on a search key word, employing a trie database including multiple trie blocks that include pointers to other trie blocks. Each trie is accessible by means of a segment of the search key. A selected section of the search key word is applied to a content addressable memory. In the event of an absence of a match of the selected section with an entry in the content addressable memory, a trie search is performed on the whole search key word. In the event of a match of the selected section with an entry in the content addressable memory, a partial trie search is performed, commencing with a first segment of the search key word after the selected section that has been matched in the content addressable memory.
