Off by default. Some complex queries (e.g. those involving categories, or proximities closer than "page") can take more time to determine exact result hit counts. In some cases it may cause timeouts. Enabling this option will determine hit counts much faster, and using less CPU, though at the expense of accuracy. The hit counts for complex queries will generally be overestimated (it will say there are more results than there really are).
