I would like to use Nest to populate the completion suggestion field into an index. After reading this ElasticSearch blog post about implementing a completion field I see you can have the following properties:
I am assuming that to load this data into an index I need to include an entity on my search object that contains the above fields?
I was able to finally load the completion field by creating several classes, and following the FluentMappingFullExample unit test, specifically the following part:
.Completion(s=>s
.Name(p=>p.Name.Suffix("completion"))
.IndexAnalyzer("standard")
.SearchAnalyzer("standard")
.MaxInputLength(20)
.Payloads()
.PreservePositionIncrements()
.PreserveSeparators()
)
For my search type entity, I created a field called suggest and made it of type CompletionField.
public class CompletionField
{
public CompletionField()
{
Input = new List<string>();
}
public List<string> Input { get; set; }
//public string Output { get; set; }
public int Weight { get; set; }
public Payload Payload { get; set; }
}
public class Payload
{
public int ID { get; set; }
}
After I loaded my entity from the db using dapper, I then looped over the results and loaded my completion field with the appropriate inputs that I wanted. I was then able to successfully call the suggest API and query on this data. I hope this helps someone else.
