your usage of the api is perfectly right. I'm not sure what's going on
there, and can't reproduce this here.
To help debug this a bit, could you please try this in the console:
results = Link.find_by_contents(query)
result = results.first
result.highlight(query, :field => :description) # returns nil
doc_num = result.document_number
# if you are on aaf trunk:
Link.aaf_index.ferret_index.highlight(query, doc_num, :field => :description)
# if on aaf stable:
Link.ferret_index.highlight(query, doc_num, :field => :description)
this would directly use ferret's highlight method. Btw, what version of
aaf do you use?
