Yes.  You can specify how many bytes to store with omindex's
--sample-size=SIZE option, with the default being 512.  It'll actually
stop at the previous word boundary before the limit.

You could use $terms to get the query terms matching the current
hit and do that, though $snippet also supports phrase queries and
wildcards which would be hard to replicate from just the individual
terms.
