As a parameter to the index GET perhaps?

GET .../index/node/myindex?query=name:*sort=GivenNameorder=desc

2011/11/22 Peter Neubauer peter.neuba...@neotechnology.com

 I agree.
 Sending arbitrary Groovy is not what you want a database to execute. Do you
 see any good index - neutral way to expose this? It's even very relevant to
 Cypher...

  Hi Guys,
 
  What is the easiest way for me to build a custom full text sort for
 lucene
  in Neo4j, the thing is, we use the REST API to query the index, and I
 would
  like to apply a custom sort
 
  e.g.
 
  I want to change sorting to:
  Sort by Relevance (Booster) then by IndexKey1 then by indexKey2.
 
  Currently, we have the default sort via the query parser api, but it is
  not powerful enough(
  http://lucene.apache.org/java/3_1_0/queryparsersyntax.html).
 
  Any ideas, how we could do this, and still leverage the REST API for
 index
  queries?
 
  Cheers

Maybe,
but that means that every index needs to have the notion of sorting
and ordering?

I would be nice if we can introspect and see if the indexes available
support ordering.
