Why is keyword_searches.search_count column always showing 0 even with multiple searches on the text string?

Environment:

All sites 

Resolution:

The keyword_searches.search_count column is no longer a supported data point. As a result, it will always show as zero and subsequent processing and aggregation is not done on this column. The modern replacement for the keyword_searches table are the various KF actionable analytics around the kf_searches table (usually the kf_search_stats - based reports).
