FosElasticaBundle: How to search using multiple keywords? - symfony

Question

this is working for me ok: $results = $finder->find('muj*');
but when I try $results = $finder->find(array('muj*', 'hom*)); I get this:
SearchPhaseExecutionException[Failed to execute phase [query], all
shards failed; shardFailures {[qTMnzJeGTu-YVumR2xLW1Q][search]1:

nested: SearchParseException[search: from[-1],size[-1]: Parse

For me it is strange since the docs say that find() admits an array as parameter.
