Subject Re: Bindable Baz.bind(DataContext) issue

Thank you Vladimir and Andrei, 

Well I thought that the query wasn't executed correctly since it gave me no results but I
just found out this was another issue... So this is working fine even with an array of terms
for filters. 
But it can be useful later to know where this is done :) 

Thanks again, 

Dylan

Dylan, 

The query translation is happening in PredicateAnalyzer 
<https://github.com/apache/calcite/blob/master/elasticsearch/src/main/java/org/apache/calcite/adapter/elasticsearch/PredicateAnalyzer.java#L326>

(called inside ElasticsearchFilter). 
Any reason why you want match query instead of term 
<https://www.elastic.co/guide/en/elasticsearch/guide/current/term-vs-full-text.html>

?
