I have installed **ElasticSearch 6.1.2** and also installed **ltr plugin**...  
And when I am executing below query, it returned following error.

**Note: hotels is index name**

var searchResponse = lowlevelClient.Search("hotels", @"  
""query"": {  
""multi\_match"": {  
""query"": ""hotel"",  
""fields"": [""name"", ""address""]  
}  
},  
""rescore"": {  
""query"": {  
""rescore\_query"": {  
""sltr"": {  
""params"": {  
""keywords"": ""hotel""  
},  
""model"": ""8"",  
}  
}  
}  
}");

**Error in Response**

"Expected [START\_OBJECT] but found [VALUE\_STRING]"
