------------------------------------
Summary: SpatialStrategy DocValues & FieldType customizability
Key: LUCENE-5802
URL: https://issues.apache.org/jira/browse/LUCENE-5802
Project: Lucene - Core
Issue Type: Improvement
Components: modules/spatial
Reporter: David Smiley
The SpatialStrategy API is a simple facade to index spatial data and query by
it in a consistent way, hiding the implementation. For indexing data, it has
one applicable method:
{code:java}
public abstract Field[] createIndexableFields(Shape shape);
{code}
The base abstraction provides no further configuration. BBoxStrategy and
PointVectorStrategy have a way to set the precisionStep of the underlying
Double trie fields. But none have a way to use Floats, and none have a way to
specify the use of DocValues (and which type). Perhaps there are other
plausible nobs to turn. It is actually more than just indexing since at search
time it may have to change accordingly (e.g. search difference between Float &
Double). PrefixTreeStrategy is likely to soon deprecate/remove any
applicability here (see LUCENE-5692).
If there is no change that could reasonably be made to SpatialStrategy itself,
what is the pattern that BBoxStrategy and others should use?
