Re: Best way to gather span/token positions from query? (mis-posted to dev list...)

[Otis Gospodnetic <ot...@yahoo.com>]

Sean,

I haven't looked into this very closely yet, but since you are on the bleeding edge Solr and are looking for pointers, let me point out the new FieldAnalysisRequestHandler and DocumentAnalysisRequestHandler.


[otis@localhost src]$ ff Field\*java | grep Handler.java
./java/org/apache/solr/handler/FieldAnalysisRequestHandler.java

[otis@localhost src]$ ff Document\*java | grep Handler.java
./java/org/apache/solr/handler/DocumentAnalysisRequestHandler.java

Does that work for you?
