Read through the documentation at
http://github.com/rnewson/couchdb-lucene
(Keep scrolling further down the page)

When you call rec.add() (And you can call add() more than once per 
function), there is an optional second argument to set the indexing options:

The two that you'd probably find useful are:

doc.add(doc.subject, {"field":"subject"});
If you explicitly name the field, your query must look like q=subject:Foo

and
doc.add(doc.subject, {"stored":"yes"});
This stores the value inside the result - so that it will be shown even 
without include_docs=true.
(If you want the field shown but don't want to search on it, also add 
"index":"not_analyzed" to the options object.)

The options are shown on the web page in the "The Defaults Object" table 
- further on are lots of examples.
