ElasticSearch在列表上搜索 <Guid> 使用Nest C＃

Question

I used to have type Person with field Guid MetroStation , and I was searching in elastic:

.Query(q => q.Term(tr => tr.Field(fl => fl.MetroStation).Value(MyMetroStation))

Now am changing Guid to List<Guid> . How can I search in elastic for this?

Answer 1

You won't need to change your search in any way if you are looking to find Person documents where the MetroStation Guids contain the Guid in the query.

If you're looking for Person documents where the MetroStation Guids contain exactly what is in the query, then you might consider also indexing the number of Guids in the collection to also query on . You can achieve this without indexing the count by using a script query, but if you're looking for performance, then indexing the count will likely perform better (measure it for your use case).
