AND operator does return result with both search terms

[ferdiga]

the AND operator (or may be xxxx +yyyy) as mentioned here
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#query-string-syntax

should return only results matching both criteria

currently it works like an OR operator.

+ means that word must be present. Thus, you need to add it to each word.

if not described in help text no unexperienced user will search "+john +claire" to get the results he is looking for,
or "+john -claire"

@ferdiga ah thank you! I'd done lots of tests with AND and OR, with and without quotation marks. Now at least I've got the answer ! :-)
