Update  
trying the approach shown here although I'd prefer to use just the Java API [https://discuss.elastic.co/t/cannot-set-up-script-score-for-dense-vector-using-java-rest-api/238849/3](https://discuss.elastic.co/t/cannot-set-up-script-score-for-dense-vector-using-java-rest-api/238849/3). This gets executed but all scores are 1.0 - only the match\_all query gets executed. What I'm doing wrong?

```
  SearchTemplateRequest request = new SearchTemplateRequest();
    request.setRequest(searchRequest);
    request.setScriptType(ScriptType.INLINE);

    def script =
            "{ \"query\": " +
                    "{" +
                    " \"script_score\": { " +
                    " \"query\": { " +
                    " \"query_string\" : { " +
                    " \"query\" : \"" + "match_all" + "\", " +
                    " : \"{}\" " +
                    " } " +
                    " }, " +
                    " \"script\": { " +
                    " \"source\": \"cosineSimilarity( " + vectors+ ",'title_vector') + 1.0\" " +
                    " } " +
                    " } " +
                    "}" +
                    "} ";
    request.setScript(script);
    SearchResponse s = elastic.search(request.getRequest(), RequestOptions.DEFAULT)
```
