[PATCH] Efficiently retrieve sizes of field values
--------------------------------------------------
Key: LUCENE-762
URL: http://issues.apache.org/jira/browse/LUCENE-762
Project: Lucene - Java
Issue Type: New Feature
Components: Store
Affects Versions: 2.1
Reporter: Chuck Williams
Sometimes an application would like to know how large a document is before
retrieving it. This can be important for memory management or choosing between
algorithms, especially in cases where documents might be very large.
This patch extends the existing FieldSelector mechanism with two new
FieldSelectorResults: SIZE and SIZE_AND_BREAK. SIZE creates fields on the
retrieved document that store field sizes instead of actual values.
SIZE_AND_BREAK is especially efficient if one field comprises the bulk of the
document size (e.g., the body field) and can thus be used as a reasonable size
approximation.
