 ======Indexing Using SOLR======
@@ Line 6: / Line 9: @@
 There is only rudimentary, partial support in //GLI// for building a Greenstone collection with solr as the indexer. At present, GLI will preserve solr-specific elements, such as the ''option'' subelement of ''index'' mentioned below, as well as ''solr'' and ''facet'' elements. Building a SOLR collection in GLI has 2 drawbacks in Greenstone 3.06rc1:
-  * Building a solr collection in GLI will stop the Greenstone server before building the collection and restart it when the collection has been rebuilt. In more recent versions of GS3 this is not a problem.
+  * Building a solr collection in GLI will stop the Greenstone server before building the collection and restart it when the collection has been rebuilt. In more recent versions of GS3 this is no longer a problem, as newer GS3 versions do not stop and start the server for building a solr collection any more.
   * Java 7+ is needed to successfully build a solr collection in GLI, at least on Windows. For this to work, you will first need to have a JDK 7 installed on your machine (with the JAVA_HOME environment variable set up, and with JAVA_HOME/bin added to your PATH environment variable). Secondly, you will need to move your Greenstone 3 installation's ''packages/jre'' out of the way before running GLI, so that GLI finds your Java 7 instead.
-====== Accessing Solr Admin ======
+===== Accessing Solr Admin =====
-  * In the case of a Greenstone server and client running on the same PC, open up http://127.0.0.1:8383/solr in your browser
+  * In the case of a Greenstone server and client running on the same PC, open up in your browser
+     * http://127.0.0.1:8383/solr (Solr4)
+     * http://127.0.0.1:7983/solr (Solr9 - gs 3.13 and later)
   * In the case of a remote Greenstone server, you need to forward ports. Assuming the default GS3 port 8383, on a Linux terminal you'd do:\\ ''ssh -L 8383:127.0.0.1:8383 <greenstone-server-machine>''
+  * If you are proxying localhost with apache, you'll need to add the appropriate lines to your /etc/httpd/conf.d/<servername>-le-ssl.conf, for example:
+<code>
+ ProxyPass /solr/ http://localhost:7983/solr/
+ ProxyPassReverse /solr/ http://localhost:7983/solr/
+</code>
+Then restart httpd

+Click on your core in the drop down core list on LHS. Then you can click analysis. You can select a field, then type in some text into the index box and the query box. This will show you what processes are happening on your text for indexing and querying.
