  === Recommended fields ===
  While these fields aren't strictly mandatory (Solr will run if you remove 
them fully), Bad Things happen in some situations if they aren't defined. We 
recommend that you leave these fields alone. If you don't use them, there's no 
appreciable penalty.
   * id - Almost all Solr installations have this field defined as the 
<uniqueKey> (see below). 
-  * _version_ <!> [[Solr4]] - This field is used for optimistic locking in 
[[http://wiki.apache.org/solr/SolrCloud|SolrCloud]] and it enables 
[[http://wiki.apache.org/solr/RealTimeGet|Real Time Get]]. If you remove it you 
must also remove the transaction logging from solrconfig.xml, see 
[[http://wiki.apache.org/solr/RealTimeGet|Real Time Get]].
+  * _version_ <!> [[Solr4.0]] - This field is used for optimistic locking in 
[[http://wiki.apache.org/solr/SolrCloud|SolrCloud]] and it enables 
[[http://wiki.apache.org/solr/RealTimeGet|Real Time Get]]. If you remove it you 
must also remove the transaction logging from solrconfig.xml, see 
[[http://wiki.apache.org/solr/RealTimeGet|Real Time Get]].

    * To use interactively, requires [[TermVectorComponent]]
    * Corresponds to TV button in Luke, and V field attribute.
   * `omitTermFreqAndPositions=true|false` <!> [[Solr1.4]]
-   * If set, omit term freq, positions and [[Payloads|payloads]] from postings 
for this field. This can be a performance boost for fields that don't require 
that information and reduces storage space required for the index. Queries that 
rely on position that are issued on a field with this option will silently fail 
to find documents.
