Hi,
When I try to run a query with a range query rescorer, Elasticsearch
(version 1.3.2) will raise an java.lang.UnsupportedOperationException
on org.apache.lucene.search.Query.extractTerms. The exact class raising the
exception was NumericRangeQuery in my test.
After some investigations, I found that this occurs when ES try to extract
terms in each rescorer (source
https://github.com/elasticsearch/elasticsearch/blob/v1.3.2/src/main/java/org/elasticsearch/search/dfs/DfsPhase.java#L75).
Everything is working fine for the search query as it is rewritten before
the "extractTerms" method is called (source
https://github.com/elasticsearch/elasticsearch/blob/v1.3.2/src/main/java/org/elasticsearch/search/dfs/DfsPhase.java#L67
).
If I rewrite myself the query as ES would do, everything seems to work
fine. This works because Lucene does not extract terms encapsulated in
filter inside ConstantScoreQuery (source
https://github.com/apache/lucene-solr/blob/lucene_solr_4_9_0/lucene/core/src/java/org/apache/lucene/search/ConstantScoreQuery.java#L98-L103
).
You can find the curl recreation is this gist
