Apache Solr Reference Guide Covering Apache Solr 6.0

To export the full sorted result set you'll want to use a request handler explicitly configured to only run the "query"
component, using the the export "rq" and "wt" params.
An "/export" request handler with the appropriate configuration is included in the techproducts example so
lrconfig.xml. If however, you would like to add it to an existing solrconfig.xml, you can add a section like
this:
{!xport}
xsort
false
query
Note that this request handler's properties are defined as "invariants", which means they cannot be overridden by
other properties passed at another time (such as at query time).
Requesting Results Export
Once the /export request handler is defined, you can use it to make requests to export the result set of a
query.
All queries must include sort and fl parameters, or the query will return an error. Filter queries are also
supported. Results are always returned in JSON format.
Here is an example of what an export request of some indexed log data might look like:
http://localhost:8983/solr/core_name/export?q=my-query&sort=severity+desc,timestamp+
desc&fl=severity,timestamp,msg
Specifying the Sort Criteria
The sort property defines how documents will be sorted in the exported result set. Results can be sorted by any
field that has a field type of int,long, float, double, string. The sort fields must be single valued fields.
Up to four sort fields can be specified per request, with the 'asc' or 'desc' properties.
Specifying the Field List
The fl property defines the fields that will be exported with the result set. Any of the field types that can be
sorted (i.e., int, long, float, double, string) can be used in the field list. The fields can be single or multi-valued.
However, returning scores and wildcards are not supported at this time.
Distributed Support
So Streaming Expression for distributed support.
