I am trying to disable fuzziness in my ElasticSearch query. The issue is that a search for medication returns lots of hits for medical. My query is below. The fuzzy_max_expansions arg doesn't have any effect. If I add a fuzziness arg it breaks the query altogether.
I am using Wordpress and Elasticpress to query elasticsearch.
[query] => Array ( [simple_query_string] => Array ( [query] => medication [fields] => Array (  => post_title  => post_excerpt  => post_content ) [default_operator] => and [flags] => all [fuzzy_transpositions] => false [fuzzy_max_expansions] => 0 ) )
