Multi Terms search NEST C#

问题:

I want to do a search matching multiple values ( an array of values ) like this :

var result1 = _client.Search<type1>(s => s             .Fields(f => f.trip_id)             .Query(q => q                 .Terms(t => t.arg1, value1)).Take(_allData))                 .Documents.Select(d => d.arg2).ToArray();  var result2 = _client.Search<type2>(s => s                       .Query(q => q                           .Terms(t => t.arg3, result1))                           .Take(_allData)                           ).Documents.Select(s => s.ar3).ToList(); 

How can I do ? I was thinking about facets but I don't see how I can do it. The only way for now that works is with a foreach iterator which is not really effective...

Thanks for your help.

回答1:

You can express multiple queries like so:

.Query(q=>q.Terms(t=>t.arg3, result1) && q.Terms(t=>t.arg1, value1)) 

Be sure to read the documentation on writing queries to discover all the good stuff NEST has to offer.

Orelus, I'd like to use your solution with

.And( af=>af.Term(...), af=>af.Term(...) ) 

I don't understand where this fits, here's an example of my non-working filter

var results = client.Search<music>(s => s     .Query(q => q         .Filtered(f => f.             Filter(b => b.Bool(m => m.Must(                 t => t                     .Term(p => p.artist, artist)                      && t.Term(p2 => p2.year, year)                 )                 )             )         )     )     );
