How do I dynamically create multiple filters on one search query? about elasticsearch-net HOT 2 CLOSED

Hi clarkb,

I've committed some additional unit tests that do a better job describing how to branch queries then i could probably type up:

https://github.com/Mpdreamz/NEST/blob/29e5973332f89fc48ccfced3944cd935544230df/src/Nest.Tests.Unit/Query/Bool/StaticBoolQueryTests.cs

I did a longish write up here on how to dynamically generate searchdescriptors here:
#52

I wrote that before NEST had proper &&, || and ! support and before it had a static Query, Query<T> , Filter and Filter<T> of which to spawn queries at will.

Hopefully i get around to writing some proper documentation on all the different query generation paths you can take (NEST has several) somewhere next week.

I hope this for now answers your question though.let me know if it doesn't!

It still wasn't clear to me how to do this based on the additional tests, but I came up with the following:

var filter = Filter<Part>.Term(x => x.DivisionID, divisionId);
if (classId != "")
{
    filter &= Filter<Part>.Query(f => f.QueryString(q => q.Query(classId).OnField(field => field.ClassID)));
}
if (subclassId != "")
{
    filter &= Filter<Part>.Query(f => f.QueryString(q => q.Query(subclassId).OnField(field => field.SubClassID)));
}

Would that be the right way to do it? I now have to do something similar but this time I need to create a multiple-value "or" filter. Using the above example, I'd have a string array of division IDs and need to match on any of them. The array could be any length, so I'm not sure if I have to loop through it and add an or filter for each value or if I can pass in the string array to something as the set of values to match.
