The XSLT UpdateRequestHandler lets you index arbitrary XML documents to Solr using on-the-fly XSLT transformation to Solr's update XML.

(warning) Solr3.4

Requirements

(warning) In Solr4.0, XSLT support is included in the standard XML UpdateRequestHandler

  <requestHandler name="/update" class="solr.UpdateRequestHandler"/>

Note, requests need to include Content-type:application/xml or Content-type:text/xml

When the "tr=XXX" parameter is present, it will be used to transform the incomming XML

(warning) Solr3.4 is the first version with XSLT support for updates.

The XSLT request handler needs to be configured in solrconfig.xml This should already be present in the example solrconfig.xml

  <!-- XSLT Update Request Handler
       Transforms incoming XML with stylesheet identified by tr=
  -->
  <requestHandler name="/update/xslt"
                   startup="lazy"
                   class="solr.XsltUpdateRequestHandler"/>

Methods of uploading XML files

An arbitrary XML for which you have a transformation stylesheet may be uploaded to Solr by sending the data to the /solr/update/xslt URL, and specifying the stylesheet in the &tr=mySheet.xsl parameter. All of the normal methods for uploading content are supported.

Examples

Transform query result XML

Indexing a Solr XML query result file. This could be an export from an older search index that you want to migrate. For this we have a style sheet updateXml.xsl which was new in (warning) Solr3.6

  1. Download the search result xml, let's call it "queryresult.xml" 2. Feed your data through XSLT update handler selecting the correct style sheet
curl "http://localhost:8983/solr/update/xslt?commit=true&tr=updateXml.xsl" -H "Content-Type: text/xml; charset=utf-8" --data-binary @queryresult.xml
