I've tried to write the plugin code.
Currently I do:
AddUpdateCommand addUpdateCommand = new
AddUpdateCommand(solrQueryRequest);
DocIterator iterator = docList.iterator();
SolrIndexSearcher indexReader =
solrQueryRequest.getSearcher();
while (iterator.hasNext()) {
Document document = indexReader.doc(iterator.nextDoc());
SolrInputDocument solrInputDocument = new
SolrInputDocument();
addUpdateCommand.clear();
addUpdateCommand.solrDoc = solrInputDocument;
addUpdateCommand.solrDoc.setField("id",
document.get("id"));
addUpdateCommand.solrDoc.setField("my_updated_field",
new_value);
updateRequestProcessor.processAdd(addUpdateCommand);
}
But this is very expensive since the update handler will fetch again the
document which I already hold at hand.
Is there a safe way to update the lucene document and write it back while
taking into account all the Solr related code such as caches, extra solr
logic, etc?
I was thinking of converting it to a SolrInputDocument and then just add the
document through Solr but I need first to convert all fields.
Thanks in advance,
Avner
