This parameter enables and disables the use of statistical sampling for calculating the terms in feed facets. This provides significantly improved runtime performance and reduced memory usage.
True, fuzzy faceting of feed facets begins when the following configuration parameters reach a specified threshold:
CoreServicesFuzzyFeedFacetsThreshold(Default = 10000)
CoreServicesFuzzyFeedFacetsSamplingPerc(Default = 0)
Enabling this setting improves runtime performance and reduces memory usage. Disabling this setting increases the accuracy of the resulting data, but slows down performance.
