There is some support in DocValues for multiple values per document, but they still ultimately must reduce down to a single value coming out of the function. See the VectorValueSource as an example. In other words, the API is there, but nothing implements it. I imagine you could use the UninvertedField to back a ValueSource and have it leverage the DocValues that return multiple values.
If you can specify your use case, that might help define a solution. On Feb 17, 2011, at 3:00 PM, Bill Bell wrote: > Yes I know all too well.
