public static final String DEFAULT_QTYPE
public static final Map<String,QParserPlugin> standardPlugins
QParserPlugin
has own instance of standardPlugins.
This leads to cyclic dependencies of static fields and to case when NAME field is not yet initialized.
This result to NPE during initialization.
For every plugin, listed here, NAME field has to be final and static.public abstract QParser createParser(String qstr, SolrParams localParams, SolrParams params, SolrQueryRequest req)
