I feel a bit dumb asking this, but how do I use it? Eg, I have a data entry C.L. Bowes and J.D. Richardson and G. Cumming and K. Horsfield, Effect of breathing pattern on gas mixing in a model with asymmetrical alveolar ducts, JAP, vol. 58, pp. 18-26, 1985.
Using the simple search "gas", I can find it. But the regex "g.s" doesn't work. (Yes, I checked the regex button.) In fact, I can't get any regex to work. I guess I'm doing something dumb... Does anyone use this facility? If so, can someone help me out? Angus
