Hash on the first letter of the recipe name: In general, the index set is a tree whose leaves consist of pointers into a sequence set, Each node in the index set points to three lower nodes, Example: find pBR322.f2 assuming a Btree index on fragment name, we take the middle node, which contains pBR322.f2, If there are more layers, continue repeating the algorithm until you get to the sequence set, Indexing can substantially improve access times, Deciding what field to index on depends on usage patterns, You can have multiple indices, but that substantially increases insert time and space requirements, Knuth, D.
