Rescoring with levenshtein


(janek sendrowski) #1

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?
