Pipelined query processing over a term-wise distributed inverted index has superior throughput at high query multiprogramming levels. However, due to long query latencies this approach is inefficient at lower levels. In this paper we explore two types of intra-query parallelism within the pipelined approach, parallel execution of a query on different nodes and concurrent execution on the same node. According to the experimental results, our approach reaches the throughput of the state-of-the-art method at about half of the latency. On the single query case the observed latency improvement is up to 2.6 times.
