Greetings,

The following query does not work with msearch and NodeJS client:

{  
\_type: 'Account',  
\_source\_exclude: ['timestamp', 'mainUserId']  
},  
{query: {constant\_score: {filter: {term: {mainUserId: params.mainUserId}}}}}

I also tried \_sourceExclude, \_source: {exclude: ...}, and [...].join() with no luck

Regards

Actually source filtering in general does not always work with multi search JavaScript Node API.

No answer? 😥
