 Once some Dataverse collections, datasets, and files have been created and indexed, you can experiment with searches directly from Solr at http://localhost:8983/solr/#/collection1/query and look at the JSON output of searches, such as this wildcard search: http://localhost:8983/solr/collection1/select?q=*%3A*&wt=json&indent=true .

+Updating the Solr Schema (Developers)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Both developers and sysadmins need to update the Solr schema from time to time. One difference is that developers will be committing changes to ``conf/solr/schema.xml`` in git. To prevent cross-platform differences in the git history, when running the ``update-fields.sh`` script, we ask all developers to run the script from within Docker. (See :doc:`/container/configbaker-image` for more on the image we'll use below.)
+
+.. code-block::
+
+    curl http://localhost:8080/api/admin/index/solr/schema | docker run -i --rm -v ./docker-dev-volumes/solr/data:/var/solr gdcc/configbaker:unstable update-fields.sh /var/solr/data/collection1/conf/schema.xml
+
+    cp docker-dev-volumes/solr/data/data/collection1/conf/schema.xml conf/solr/schema.xml
+
+At this point you can do a ``git diff`` and see if your changes make sense before committing.
+
+Sysadmins are welcome to run ``update-fields.sh`` however they like. See :ref:`update-solr-schema` in the Admin Guide for details.
