| Default | 0 | Use the default calculation method. Sphinx will use 'Haversine' in versions prior to 2.2.1 and 'Adaptive' starting with 2.2.1 |
| Haversine | 1 | Use the Haversine algorithm (precise but also very calculation intensive). |
| Adaptive | 2 | Use the Polar flat-Earth algorithm (good precisison, though not as good as Haversine, but very fast). |
