The "DataImportHandler" page has been changed by martijnvg:

Added documentation for SolrEntityProcessor

  See for a patch that extends LineEntityProcessor
to support fixed-width and delimited files without needing to use a Transformer.
+ === SolrEntityProcessor === 
+ <<Anchor(plaintext)>> <!> [[Solr3.6]]
+ This EntityProcessor imports data from different Solr instances and cores. The data is retrieved
based on a specified (filter) query.
+ This EntityProcessor is useful in cases you want to copy your Solr index and slightly want
to modify the data in the target index. In some
+ cases Solr might the only place were all data is available. The SolrEntityProcessor can
only copy fields that are stored in the source index.
+ The SolrEntityProcessor supports the following attributes:
+ * url The url of the source Solr instance / core
+ * query The main query to execute on the source index.
+ * fq Any filter query to execute in the source index. (Comma seperated) 
+ * rows The number of rows to return for each iteration. Defaults to 50.
+ * fields What fields to fetch from the source index. (Comma seperated)
+ * format The format (javabin|xml) to use as reponse format. Use xml if the Solr versions
don't match.
+ * timeout. The query timeout in seconds. This can be used as a fail-safe to prevent the
indexing session from freezing up. By default the timeout is 5 minutes.
+ Example:
+ {{{
+ <dataConfig>
+   <document>
+     <entity name="sep" processor="SolrEntityProcessor" url="http://localhost:8983/solr/db
" query="*:*"/>
+   </document>
+ </dataConfig>
+ }}}
