We evaluate how well EOBNR waveforms, obtained from the effective one-body formalism, perform in detecting gravitational wave (GW) signals from binary black hole (BBH) coalescences modelled by numerical relativity (NR) groups participating in the second edition of the numerical injection analysis (NINJA-2). In this study, NINJA-2 NR-based signals that are available in the public domain were injected in simulated Gaussian, stationary data prepared for three LIGO-Virgo detectors with early Advanced LIGO sensitivities. Here we studied only non-spinning BBH signals. A total of 2000 such signals from 20 NR-based signal families were injected in a two-month long data set. The all-sky, all-time compact binary coalescence (CBC) search pipeline was run along with an added coherent stage to search for those signals. We find that the EOBNR templates are only slightly less efficient (by a few percent) in detecting non-spinning NR-based signals than in detecting EOBNR injections. On the other hand, the coherent stage improves the signal detectability by a few percent over a coincident search.
