Add to Solr (Data) (Solr)


This operator adds an example set to Solr.


To connect to a Solr server, you have to specify a Solr connection. This comprises the URL of a Solr server and an optional user/password combination for authentication. Typically, the Solr server URL ends with the string '/solr'.

The next step is to select a collection on the server. A collection can be imagined as a table. It is composed of several columns, which are called Solr fields. A Solr field has a type (e.g. number) and a key (the name of the column). Each entry in Solr can be imagined as a row and contains values for the respective fields.

A RapidMiner example set has a very similar structure. It also can be imagined as a table. Therefore every row of RapidMiner is added as row in Solr. The RapidMiner attributes are used as Solr collection fields.
