title: What is the use of "multiValued" field type in Solr?
body: <p>I'm new to Apache Solr.  Even after reading the <a href="http://wiki.apache.org/solr/SchemaXml">documentation</a> part, I'm finding it difficult to clearly understand the functionality and use of the <code>multiValued</code> field type property. </p>
  
  <p>What internally Solr does/treats/handles a field that is marked as  <em>multiValued</em>? </p>
  
  <p>What is the difference in indexing in Solr between a field that is <em>multiValued</em> and those that are not?</p>
  
  <p>Can somebody explain with some good example?</p>
  
  <p>Doc says:</p>
  
  <blockquote>
    <p><em>multiValued=true|false</em></p>
    
    <p>True if this
    field may contain multiple values per
    document, i.e. if it can appear
    multiple times in a document</p>
