Hi all,
I have discovered a strange thing with Dismax and Elevation and hope
someone can enlighten me what to do.
Whenever I search for something using the elevation Request Handler the
hits are from a normal Lucene query (with elevated results if the search
term was defined in elevation.xml). Elevation works, but only with dismax.
Whenever I search using the dismax handler with elevated terms,
elevation only works if I turned off sharding. Using shards results in
an exception (IndexOutOfBoundsException). Complete message is listed below.
Is this a bug or did I miss anything to switch in configuration? I also
tried to add
dismax
to elevation request handler in solrconfig.xml, but that didn't help.
The elevator component is integrated into the dismax search handler in
.
Any hints appreciated!
Thank you in advance
Oliver
My Solr-configuration for elevation request handler and elevation search
component look like that:
text
elevate.xml
explicit
elevator
debug
The complete exception message I get from searching with dismax,
elevation and sharding:
