Subject Re: Solr 5.0 --> "IllegalStateException: unexpected docvalues type NONE" on result grouping
Date Wed, 11 Mar 2015 22:29:12 GMT

1) the error message you posted doesn't appear to have been copied 
verbatim (note: "...or dex...") ... please proivde the *exact* error you 
are getting -- ideally with full stack trace from the solr logs.

2) the <field/> you posted doens't match the field name in your error 

3)providing a <field/> w/o the <fieldType/> makes it hard to guess 
exactly what settings you are using (ie: is "docValuesFormat" specified on 
the fieldType?)

4) You said you are using result grouping, but you haven't actually shown 
us an example of what your request (with all params) looks like ... 
there's nohting in your email to even indicate grouping is involved.

Details matter...

(PS: assuming no obvious mistakes, it would be helpful to know if you can 
reproduce this problem using your same exact same configs & schema with a 
newly built 5.0 index, or if it *only* affects you when you upgrade and 
use an existing index from 4.7)

:     on result grouping
: Hi,
:    I've a field which is being used for result grouping. Here's the field
: definition.
: <field name="ADDedup" type="string" indexed="true" stored="true"
: multiValued="false" required="false" omitNorms="true"  docValues="true"/>
: This started once I did a rolling update from 4.7 to 5.0. I started getting
: the error on any group by query --> "SolrDispatchFilter null:java.lang.
: IllegalStateException: unexpected docvalues type NONE for field 'ADSKDedup'
: (expected=SORTED). Use UninvertingReader or dex with docvalues."
: Does this mean that I need to re-index documents to get over this error ?
: Regards,
: Shamik
