  Say we're returning a lot of records here and want to reduce them by including the title (or if no title exists, the name) attribute of the thing that was tagged along with the results. Change the following line in the ''to_docs'' query above:
  
  {{{
- // map(doc.tags[i], null);
+ // emit(doc.tags[i], null);
  // becomes
- map(doc.tags[i], doc.title || doc.name);
+ emit(doc.tags[i], doc.title || doc.name);
  }}}
  
  Optionally, this view could be named to_docs_with_title so as to be available only if the extra data is desired.
