Abstract

In-place and merge-based index maintenance are the two main competing strategies for on-line index construction in dynamic information retrieval systems based on inverted lists. Motivated by recent results for both strategies, we investigate possible combinations of in-place and merge-based index maintenance. We present a hybrid approach in which long posting lists are updated in-place, while short lists are updated using a merge strategy. Our experimental results show that this hybrid approach achieves better indexing performance than either method (in-place, merge-based) alone.
