>
> I propose adding LATENT FieldSelectorResult
> this would be similar to LAZY_LOAD except that it would NEVER cache the
> stored value
> This will be useful for very large fields that should always go direct to
> disk (because they will take so much memory)
> when caching Documents returned from a Searcher, the large field may be
> initially requested as LAZY_LOAD, however once someone reads this field, it
> will then get locked into memory. if this Document (and others like it) are
> cached, it can start to use a very large amount of memory for these fields
> Contract for FieldSelectorResult.LATENT should be that it will always be
> pulled direct from the IndexInput and never be persisted in memory as part of
> a Fieldable
> I could prepare a patch if desired
