Abstract
A system and method for allocating the blocks of index file to the postings for words found in documents of a database is disclosed. The index file is provided with blocks that is partitioned into successively decreasing levels of blocks in size. The blocks in each successive level have same size and the sum of sizes of blocks in each successive level equals the size of initial block. An information retrieval interface allocates to the postings for a word a free block in the level the size of which is closest to the size of postings for the word in the index file.
