Apache Solr Reference Guide Covering Apache Solr 6.0

curl "http://localhost:8983/solr/techproducts/update/extract?&extractOnly=true"
--data-binary @example/exampledocs/sample.html -H 'Content-type:text/html'
The output includes XML generated by Tika (and further escaped by Solr's XML) using a different output format
to make it more readable (`-out yes` instructs the tool to echo Solr's output to the console):
bin/post -c techproducts -params "extractOnly=true&wt=ruby&indent=true" -out yes
example/exampledocs/sample.html
Sending Documents to Solr with a POST
The example below streams the file as the body of the POST, which does not, then, provide information to Solr
about the name of the file.
curl
"http://localhost:8983/solr/techproducts/update/extract?literal.id=doc6&defaultField
=text&commit=true" --data-binary @example/exampledocs/sample.html -H
'Content-type:text/html'
Sending Documents to Solr with Solr Cell and SolrJ
SolrJ is a Java client that you can use to add documents to the index, update the index, or query the index. You'll
find more information on SolrJ in Client APIs.
Here's an example of using Solr Cell and SolrJ to add documents to a Solr index.
First, let's use SolrJ to create a new SolrClient, then we'll construct a request containing a ContentStream
(essentially a wrapper around a file) and sent it to Solr:
public class SolrCellRequestDemo {
public static void main (String[] args) throws IOException, SolrServerException {
SolrClient server = new
HttpSolrClient("http://localhost:8983/solr/my_collection");
ContentStreamUpdateRequest req = new
ContentStreamUpdateRequest("/update/extract");
req.addFile(new File("my-file.pdf"));
req.setParam(ExtractingParams.EXTRACT_ONLY, "true");
NamedList result = server.request(req);
System.out.println("Result: " + result);
}
This operation streams the file my-file.pdf into the Solr index for my_collection.
The sample code above calls the extract command, but you can easily substitute other commands that are
supported by Solr Cell. The key class to use is the ContentStreamUpdateRequest, which makes sure the
ContentStreams are set properly. SolrJ takes care of the rest.
Note that the ContentStreamUpdateRequest is not just specific to Solr Cell. You can send CSV to the CSV
Update handler and to any other Request Handler that works with Content Streams for updates.
