H Shawn, Thank you very much for your response!
Solr DataImportHandler "could not" directly index MongoDB collections. I used open source SolrMongoImporter project (https://github.com/james75/SolrMongoImporter) on top of Solr DIH to to directly index data of MongoDB collections. What I did was that I wrote a new Java class (public class EntryTransformer extends Transformer) to convert the ObjectId to a String and to flatten MongoDB document. Here is my data-config.xml file: <?xml version="1.0" encoding="UTF-8" ?> <dataConfig> <dataSource name="MongoSource" type="MongoDataSource" host="localhost" port="27017" database="dw_v2" /> <document name="import"> <entity processor="MongoEntityProcessor" name="Entry" collection="core_entry" query="" transformer="org.rcsb.solr.handler.dataimport.EntryTransformer"> </entity> </document> </dataConfig> So overall, I didn't change any code in the following projects. solr-dataimporthandler-7.3.1.jar solr-dataimporthandler-extras-7.3.1.jar solr-mongo-importer-1.1.0.jar Since MongoDB or other NOo-SQL database are in the trend of increasing usage, I wish that Solr will develop new tools or extend its DataImportHandler to allow directly index No-SQL document. All the best! -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
