The Extended Dismax query parser (edismax) mostly "obsoletes" Dismax except
in the sense that some apps prefer the restricted syntax of Dismax:

Subject: solr 1.4.1 -> 3.6.1; SOLR-758
Regarding https://issues.apache.org/jira/browse/SOLR-758 (Enhance
DisMaxQParserPlugin to support full-Solr syntax and to support alternate
escaping strategies.)
I'm updating from solr 1.4.1 to 3.6.1 (I'm aware that it is not beautiful).
After applying the attached patches to 3.6.1 I'm experiencing this problem:
- SEVERE: org.apache.solr.common.SolrException: Error Instantiating
QParserPlugin, org.apache.solr.search.AdvancedQParserPlugin is not a
org.apache.solr.search.QParserPlugin
at org.apache.solr.core.SolrCore.createInstance(SolrCore.java:421)
at
org.apache.solr.core.SolrCore.createInitInstance(SolrCore.java:441)
at org.apache.solr.core.SolrCore.initPlugins(SolrCore.java:1612)
[...]
These patches seems no valid anymore.
Which leads me to the more experienced users here:
- Although not directly mentioned in
https://issues.apache.org/jira/browse/SOLR-758, is there any other (new)
QParser which obsoletes the DisMax?
- Futhermore I tried to make the patches apply ("forward porting"), but
always get the error "Error Instantiating QParserPlugin,
org.apache.solr.search.AdvancedQParserPlugin is not a
org.apache.solr.search.QParserPlugin", although the class dependency is
linear:
./core/src/java/org/apache/solr/search/AdvancedQParserPlugin.java:
[...]
public class AdvancedQParserPlugin extends DisMaxQParserPlugin {
[...]
./core/src/java/org/apache/solr/search/DisMaxQParserPlugin.java:
[...]
public class DisMaxQParserPlugin extends QParserPlugin {
[...]
Thanks,
Patrick
