Abstract	Index size savings from three techniques are measured. The three techniques are: 1) eliminating common, low information words found in a "stop list" (such as: of, the, at, etc.), 2) truncating terms by eliminating word stems (such as: -s, -ed, -ing, etc.), and 3) simple data compression. Savings are measured on two moderately large collections of text. The index size savings that result from using the techniques individually and in combination are reported. The impact on query performance in terms of speed, recall and precision are estimated.
