Installation

1. Firstly you will need a copy of the Solr MongoDB Importer jar.

   Getting Solr MongoDB Importer

   1. Download the JAR from GitHub
   2. Build your own using the ant build script. You will need the JDK installed as well as Ant with Maven Ant Tasks for downloading dependencies.

2. You will also need the MongoDB Java driver 3.x JAR

3. Place both of these jar's in your Solr libaries folder (I put mine in 'lib' folder with the other jar's)

4. Add lib directives to your solrconfig.xml

<lib dir="./lib/" regex="solr-mongo-importer.*\.jar"/>
<lib dir="./lib/" regex="mongo-java-driver.*\.jar"/>

##Usage Here is a sample data-config.xml showing the use of all components

         <entity name="Product"
                 processor="MongoEntityProcessor"
                 query="{'Active':1}"
                 collection="ProductData"
                 datasource="MongoSource"
