Thanks for the response.
Couldn't I just use the highlighter and configure it to use the
alternative field to return the first 200 characters? In cases where
there is a highlighter match I would prefer to show the excerpts anyway.

Is this something wrong with this method?

Yep, you're correct. CopyField is probably your simplest option here as
Ahmet suggested.
A more complex solution would be your own response writer, but unless and
until you
index gets cumbersome, I'd avoid that. Plus, storing the copied contents
only shouldn't
impact search much, since this doesn't add any terms...

Correct me if I am wrong but I would like to return highlighted excerpts
from the document so I would still need to index and store the whole
document right (ie.. highlighting only works on stored fields)?

Is there way to limit the number of
characters returned from a stored field?
For example:
Say I have a document (~2K words) and I search for a word
that's somewhere in the middle. I would like the document to
match the search query but the stored field should only
return the first 200 characters of the document. Is there
anyway to accomplish this that doesn't involve two fields?
I don't think it is possible out-of-the-box. May be you can hack
highlighter to return that first 200 characters in highlighting response.
Or a custom response writer can do that.
But if you will be always returning first 200 characters of documents, I
think creating additional field with indexed="false" stored="true" will be
more efficient. And you can make your original field indexed="true"
stored="false", your index size will be diminished.
<copyField source="text" dest="textShort" maxChars="200"/>
