Xavier Sumba commented on GORA-555:
-----------------------------------
Hello, I am working on this issue. I have been reviewing the code and
documentation of Gora. I think we can just 1) use instance _of_ to detect the
datatype of K or 2) we can add the type to the [mapping
file|[https://github.com/apache/gora/blob/master/gora-lucene/src/test/conf/gora-lucene-mapping.xml].]
What do you think is an appropriate solution?
