ClearMash improves the knowledge itself
Enterprise Search takes the content as given. If the source is contradictory or out of date, it returns a contradictory, out-of-date answer faster than before. The bottleneck is the content.
ClearMash starts a step earlier, with whether the knowledge is worth retrieving at all: what is current, what conflicts, what is missing, what is written for the wrong audience, and what cannot be applied without an expert to interpret it.
Access to content is not the same as usable knowledge.
Find what exists, faster.
Improve what exists, then make it applicable.
What changes: the quality of the answer is dealt with before the speed of finding it, and checking it against a second source stops being routine.
