1. Add confman namespace and "confman" to exclude-result-prefixes.

   Code Block
   XML XML
   <xsl:stylesheet ... xmlns:confman="org.dspace.core.ConfigurationManager" exclude-result-prefixes="... confman">

2. Add this simple template to process Solr result. More complex date formatting can be done easily in XSLT 2.0 (see XSLT 2.0 spec), however Cocoon still uses XSLT 1.0 (see DS-995). It is currently also possible to call Java functions to do date formatting.

   Code Block
   XML XML
   <xsl:template match="/response/result/doc/date" mode="lastItem"> Last item was imported: <xsl:value-of select="substring(text(), 1, 10)"/> </xsl:template>

3. Add the following code to the place where you want the resulting text to appear:

   Code Block
   XML XML
   <xsl:variable name="solr-search-url" select="confman:getProperty('discovery', 'search.server')"/> <xsl:apply-templates select="document(concat($solr-search-url, '/select?q=search.resourcetype:2&amp;sort=dc.date.accessioned_dt%20desc&amp;rows=1&amp;fl=dc.date.accessioned_dt&amp;omitHeader=true'))" mode="lastItem"/>

   For example, to add it after the list of Recent items in Mirage, override its template like this:

   Code Block
   XML XML
   <xsl:template match="dri:referenceSet[@type = 'summaryList' and @n='site-last-submitted']" priority="2"> <xsl:apply-templates select="dri:head"/> <!-- Here we decide whether we have a hierarchical list or a flat one --> <xsl:choose> <xsl:when test="descendant-or-self::dri:referenceSet/@rend='hierarchy' or ancestor::dri:referenceSet/@rend='hierarchy'"> <ul> <xsl:apply-templates select="*[not(name()='head')]" mode="summaryList"/> </ul> </xsl:when> <xsl:otherwise> <ul class="ds-artifact-list"> <xsl:apply-templates select="*[not(name()='head')]" mode="summaryList"/> </ul> </xsl:otherwise> </xsl:choose> <xsl:variable name="solr-search-url" select="confman:getProperty('discovery', 'search.server')"/> <xsl:apply-templates select="document(concat($solr-search-url, '/select?q=search.resourcetype:2&amp;sort=dc.date.accessioned_dt%20desc&amp;rows=1&amp;fl=dc.date.accessioned_dt&amp;omitHeader=true'))" mode="lastItem"/> </xsl:template>

Multicore join queries

Solr supports join queries across multiple cores since Solr 4.0. Thus it's also supported in DSpace 4.0 (which includes Solr 4.4).

http://localhost:8080/solr/search/select/?q=*:*&fq={!join from=owningItem to=search.resourceid fromIndex=statistics}title:"Testing title"

"AND" search as default

DSpace Discovery uses the "OR" operator as default if you don't specify an operator between your keywords. So searching for "John Doe" will also return entries like "Jane Doe" and "John Connor". If you want to change that, you have to edit the schema.xml file of the Solr search core:
