Henrik,
I'm not familiar with riaktant but it looks like an invalid query is being
passed in. I.e. an empty query. This empty query causes and error in the
query parser and then it appears a segfault in the js driver.
E.g. here I replicate the error at the console:
(riak@127.0.0.1)5> search:search(<<"bucket">>, <<>>).
** exception error: no match of right hand side value
{error,{lucene_parse,"syntax error before: "}}
in function riak_search_client:parse_query/3
in call from search:search/3
