I reshuffled and simplified the old code of
FSharpNavigateToSearchServicequite a bit.Operators now show up correctly in search results.
The code previously used
Array.Parallelto collect search matches, so this was essentially not cancellable? This is replaced withAsync.Parallelwhich should behave better.Previously this service used
MemoryCachewith 10 sec lifetime. This may be controversial but I removed the MemoryCache in favor of simply caching everything in aConcurrentDictionary. This could take up maybe a few MBs in worst cases, but there should be a lot less GC and CPU activity on subsequent searches. Cache is now cleared on solution close.
