["Marius Grama (JIRA)" <ji...@apache.org>]

Marius Grama updated SOLR-7108:
-------------------------------
    Attachment: SOLR-7108.patch

Attached is a patch for the reported issue containing changes in the configuration files, ImplicitPlugins.java as well as unit tests for accuracy and failure of the PingRequestHandler.

I had a look on how the ping requests are handled and discovered within the QueryComponent line 144
{code}
String defType = params.get(QueryParsing.DEFTYPE, QParserPlugin.DEFAULT_QTYPE);
{code}
that the default query parser is the lucene parser ({code}QParserPlugin.DEFAULT_QTYPE = lucene{code}) reason why the hint {code}{!lucene}*:*{code}that the Lucene query parser should be used is not necessary. This is why I used {code}*:*{code} query parameter value.

> PingRequestHandler hard-codes this:
> {code}
> ping.initArgs.add(INVARIANTS, new NamedList<>(makeMap("echoParams", "all", "q", "solrpingquery")));
> {code}
> which unnecessarily relies on query parsing settings like default field.  In the case of the basic_configs core this causes a failed request because df isn't set appropriately).
