This is Search for metadata uploaded to DataCite's Metadata Store (MDS). It is based on Solr.

This a java servlet web application. You need a servlet container (e.g. tomcat). You also need Maven 2.2.1 and JDK 6 in your system (OpenJDK from Ubuntu works fine).
All dependencies are managed by Maven public repositories.
Solr requires a home directory to store the index and some properties. Be aware that the user running running your servlet container must have write access to this directory.
The content of solr_home has to be copied to your selected solr home directory.
All other required files will be in the war-file.
The git repository has a bunch of *.template files.
Those files are templates for the various configuration files which
are machine specific i.e. passwords, IP addresses etc.
To customise them you need to make a copy omitting .template from file name.
Now in such created file you need to adjust values according to your local environment.
MDS database specific properties.
You will need to specify JDBC string, for example:
jdbc:mysql://localhost:3306/datacite?useUnicode=true&characterEncoding=UTF8
Specify the path to your preliminarily chosen solr home directory by replacing <dir>.
Your usual log4j stuff.
mvn clean compile war:war
will create target/search.war, which is ready to be deployed.
This command will run packaged (i.e. not dynamic) war:
export MAVEN_OPTS="-Xmx2048m -Xms2048m"
mvn clean tomcat:run-war
The application can be accessed at:
Solr admin interface is available at:
Public access should only be granted for the /public path.
RedirectMatch ^/?$ /ui
ProxyPassMatch ^/?$ !
ProxyPass / ajp://localhost:<port>/search/public
After deploying the following resources are of interest:
/public/ui- search user interface/- admin interface
Data from MDS is imported via Solr's DataImportHandler. You can access it via admin interface.
Another option especially useful for cron jobs is scripts/solr-client. Simply try
export SOLR_URL=http://localhost:8080/search
scripts/solr-client import delta
for a delta import of MDS metadata. See solr-client help for usage.
