Hi,

I simply want to score the results of my "more\_like\_this\_field" query on my  
own.

Why doesn't this work?

\*{ \*

- 

```
 "query": { *

```

- 

```
       "function_score": { *

```

- 

```
               "more_like_this_field": { *

```

- 

```
                       "test_field": { *

```

- 

```
                               "like_text": "this is a test", *

```

- 

```
                               "min_term_freq" : "0", *

```

- 

```
                               "min_doc_freq": "0" *

```

- 

```
                       } *

```

- 

```
               }, *

```

- 

```
               "functions": [ *

```

- 

```
                       { *

```

- 

```
                               "script_score": { *

```

- 

```
                                       "script": "_score * 2" // just 

```

an example\*

- 

```
                               } *

```

- 

```
                       } *

```

- 

```
               ] *

```

- 

```
        } *

```

- 

```
 } *

```

Furthermore I like to calculate the score with levenshtein distance. I know  
there is a fuzzy search with levenshtein, but it's limited and also to slow.

I only want to score the top n results with it.

Is that somehow possible?
