The general recommendation is to watch the caches during normal user searches and keep increasing the size until evictions start happening. This may or may not work for your situation.
The problem is that the eviction rate does not show "lifetime in cache". So if 90% of the cache sits there indefinitely and the remaining 10% churns, the cache is fine but you'll show zillions of evictions.
