text字符串sort会先分词。可先建立filed字段。并设置为keyword
mapping
public void Mapping()
{
var response = client.IndexExists("employee");
if (!response.Exists)
{
client.CreateIndex("employee");
}
client.Map<employee>(m => m.Properties(p => p.Text(t => t.Name("last_name").Fielddata().Analyzer("english").Fields(f=>f.Keyword(k=>k.Name("raw"))))).AutoMap());
}
sort
public void Sort() { // client.Search<employee>(s => s.Query(q => q.Bool(b => b.Filter(f => f.Term(t => t.Field("last_name").Value("test01"))))).Pretty()); client.Search<employee>(s => s.Query(q => q.ConstantScore(c => c.Filter(f => f.Term(t => t.Field("age").Value("26") )))) .Sort(so => so.Descending("last_name") ) .Pretty()); }
