	Checks the internal cache for an appropriate entry, and if none is found reads the term values in `field` and returns an array of them in natural order, along with an array telling which element in the term array each document uses.

CacheEntry[]	GetCacheEntries ()
	EXPERT: Generates an array of CacheEntry objects representing all items currently in the FieldCache. NOTE: These CacheEntry objects maintain a strong refrence to the Cached Values. Maintaining refrences to a CacheEntry the IndexReader associated with it has garbage collected will prevent the Value itself from being garbage collected when the Cache drops the WeakRefrence. EXPERIMENTAL API: This API is considered extremely advanced and experimental. It may be removed or altered w/o warning in future releases of Lucene.

void	PurgeAllCaches ()
	EXPERT: Instructs the FieldCache to forcibly expunge all entries from the underlying caches. This is intended only to be used for test methods as a way to ensure a known base state of the Cache (with out needing to rely on GC to free WeakReferences). It should not be relied on for "Cache maintenance" in general application code. EXPERIMENTAL API: This API is considered extremely advanced and experimental. It may be removed or altered w/o warning in future releases of Lucene.

void	Purge (IndexReader r)
	Expert: drops all cache entries associated with this reader. NOTE: this reader must precisely match the reader that the cache entry is keyed on. If you pass a top-level reader, it usually will have no effect as Lucene now caches at the segment reader level.

Properties
StreamWriter	InfoStream `[get, set]`
	Gets or sets the InfoStream for this FieldCache.
