[ http://issues.apache.org/jira/browse/SOLR-59?page=all ]
Bertrand Delacretaz updated SOLR-59:
------------------------------------
Attachment: SOLR-59-20061102.patch
Here's a new patch (SOLR-59-20061102.patch and
SOLR-59-new-files-20061102.tar.gz).
I have added a SolrQueryResponseHeaders class to handle these (and any future)
additional information fields in the response headers.
The XML output format is a bit different, example for
http://localhost:8983/solr/select/?stylesheet=&q=apache&version=2.1&start=0&rows=10&indent=on&multi=red&multi=blue
<responseHeader>
<status>0</status>
<QTime>0</QTime>
<lst name="addInfo">
<lst name="explicitQueryParameters">
<arr name="multi">
<str>red</str>
<str>blue</str>
</arr>
<str name="rows">10</str>
<str name="start">0</str>
<str name="indent">on</str>
<str name="q">apache</str>
<str name="stylesheet"/>
<str name="version">2.1</str>
</lst>
</lst>
</responseHeader>
And the same info is available in a similar way in the JSON, Python and Ruby
response writers.
The explicitQueryParameters list is activated by the following (optional)
parameter in solrconfig.xml, which defaults to false:
<response>
<!-- Copy explicit request parameters to response? (SOLR-59) -->
<echoParameters explicit="true"/>
</response>
Default parameters are not dumped for now, adding them should only require
changing SolrQueryResponseHeaders.setStandardHeaders().
Also, DefaultSolrParams.getParameterNamesIterator() now returns all parameters
thanks to the new IteratorChain utility class (is there a better way without
copying collections? sounds fairly hairy for a simple thing).

> This patch copies the request parameters (explicit ones only, not the
> defaults) to Solr's XML output.
> It is not configurable yet, it is enabled by default and adds a
> "queryParameters" list to the responseHeader:
> <responseHeader>
> <status>0</status>
> <QTime>1</QTime>
> <lst name="queryParameters">
> <arr name="multi">
> <str>red</str>
> <str>blue</str>
> </arr>
> <str name="rows">10</str>
> <str name="start">0</str>
> <str name="indent">on</str>
> <str name="q">solr</str>
> <str name="stylesheet"/>
> <str name="version">2.1</str>
> </lst>
> </responseHeader>
> The above example includes a multi-valued parameter, "multi".
> This might still change a bit, but if someone wants to play with it or
> improve it, here you go.
