Unfortunately, there's not that kind of precise flexibility in Sphinx
(no idea if it exists in Lucene/Solr or Xapian).
However, you can put weightings on specific fields, so words that
appear in them will rank higher than words that appear in other
fields. Not quite the same as exact matches being ranked first, though.
In your define_index block, if you want model-wide defaults:
set_property :field_weights => {'name' => 10, 'description' => 5}
Or for specific searches:
Model.search 'query', :field_weights => {'name' => 10,
'description' => 5}
Any fields that aren't mentioned have a default weight of 1.
