*Howto: Use DSpace

Checkout the projects

...

 Discovery*   The Discovery Module enables your repository to have faceted searching.  
Thus a user can filter what they are looking for by grouping entries into a facet, and drill down to find the content they are interested in.  
So instead of user searching: \[ wetland + "dc.author=Mitsch, William J" + dc.subject="water quality" \], they can instead do their initial search, \[ wetland \], and then filter the results by attributes.

A website like Amazon, might do this to help you select a digital camera. You can reduce the results by price range, features, megapixels, manufacturer, etc.
The further the DSpace Discovery module is developed, the more useful that browsing can be to the researcher looking for items in your collections.

(Alternatively svn users can just regular svn co those above. Clone is for git, because git doesn't exactly do checkout)
(GIT ONLY) git svn doesn't add empty directories, so to correct that, type:

[dspace-trunk-git/dspace/\]$
mkdir -p modules/jspui/src/main/webapp 
mkdir -p modules/lni/src/main/webapp

1. discovery Reference
   For reference, look at the Dryad project {+}http://code.google.com/p/dryad/+^{Image Added} as that is using the discovery layer.
   http://code.google.com/p/dryad/ Overview
   Have both projects checked out to the same root projects folder. You will not have to modify dspace-discovery at all, but the patch will enable the dspace-trunk to use some features of dspace services, and include other libraries such as org.apache.solr that are needed.
   The discovery module essentially adds an additional core to solr. Existing was statistics, the new core is search. 
   To patch: 
   cd /path/to/project/dspace-trunk/dspace
   patch -p1 < /path/to/discovery-applied-to-dspace-trunk.patch
   If you name discovery-trunk anything other than that, you will have to modify dspace-trunk/dspace/pom.xml

ADD SOLR SEARCH
go to trunk/dspace/solr/
Add Dryad's SOLR core of search.

 
[trunk/dspace/solr/] $ svn export http://dryad.googlecode.com/svn/trunk/dryad/dspace/solr/search/ search 

edit /trunk/dspace/solr/solr.xml
add

 
<core name="search" instanceDir="search"/>

1. accordingly.
   Then the regular rebuild process applies. It may be necessary to do a mvn clean package.

In config/dspace-solr-search.cfg and dspace.cfg is a setting for:
solr.search.server = http://127.0.0.1:8080/solr^{Image Added}
Adjust that if necessary.
After the patch, you will need to set solr/home. Modify /dspace/webapps/solr/WEB-INF/web.xml to use your solr/home. 
    <env-entry>
       <env-entry-name>solr/home</env-entry-name>
       <env-entry-value>/dspace/solr</env-entry-value>
       <env-entry-type>java.lang.String</env-entry-type>
    </env-entry>

Once you've restarted your \{tomcat\} server, and SOLR is up and running, you'll need to index your content. 
\[/dspace/bin/\] ./dspace update-discovery-index
