Here is a brief example of how to use SolrJ with the
ExtractingRequestHandler:
ContentStreamUpdateRequest req = new
ContentStreamUpdateRequest("/update/extract");
req.addFile(fileToIndex);
req.setParam("literal.id", getId(fileToIndex));
req.setParam("literal.hostname", getHostname());
req.setParam("literal.filename", fileToIndex.getName());
try {
getSolrServer().request(req);
} catch (SolrServerException e) {
e.printStackTrace();
}
You'll need a request handler configured in solrconfig.xml:
<!-- Solr Cell Wiki:
http://wiki.apache.org/solr/ExtractingRequestHandler-->
<requestHandler name="/update/extract"
class="org.apache.solr.handler.extraction.ExtractingRequestHandler"
startup="lazy">
<lst name="defaults">
<!-- All the main content goes into this field... if you need to
return
the extracted text or do highlighting, use a stored field. -->
<str name="map.content">text</str>
<str name="lowernames">true</str>
<str name="uprefix">ignored_</str>
</lst>
</requestHandler>
Note that the example also shows how to use the "literal.*" parameter to add
metadata fields of your choice to the document.
Hope that helps get you started.
