  == View Generation Options ==
  There is currently one option that affects the data written into a view. To [[https://issues.apache.org/jira/browse/COUCHDB-346|include documents' local sequence numbers]] in the index, so they will appear in the query results, add the following to the design document:
+ 
  {{{#!highlight javascript
-     options : { 
+     options : {
-         local_seq : true 
+         local_seq : true
      }
  }}}
  (Unlike the querying options below, this isn't a URL parameter because it takes effect when the view index is ''generated'', not when it's ''accessed''.)

  If you specify ''?limit=0'' you don't get any data, but all meta-data for this View. The number of documents in this View for example.

  ''Note: Multiple keys request to a reduce function only supports group=true and NO group_level (identical to group_level=exact). The resulting error is "Multi-key fetchs for reduce view must include `group=true`"''

  The ''skip'' option should only be used with small values, as skipping a large range of documents this way is inefficient (it scans the index from the startkey and then skips N elements, but still needs to read all the index values to do that). For efficient paging you'll need to use ''startkey'' and ''limit''. If you expect to have multiple documents emit identical keys, you'll need to use ''startkey_docid'' in addition to ''startkey'' to paginate correctly. The reason is that ''startkey'' alone will no longer be sufficient to uniquely identify a row.
