What is Retrofit OR operator for search

Question

I basically would like to search for a query with 2 filters/tags

(e.g. 1 city in 2 countries - US OR CANADA)

ElasticSearchAPi.java

    public interface ElasticSearchAPI {
        @GET("_search/")
        Call search(
                @HeaderMap Map headers,
                @Query("default_operator") String operator,
                @Query("q") String query

        );
    }

Part of Search.java

    Retrofit retrofit = new Retrofit.Builder()
                                .baseUrl(BASE_URL)
                                .addConverterFactory(GsonConverterFactory.create())
                                .build();

                        ElasticSearchAPI searchAPI = retrofit.create(ElasticSearchAPI.class);

                        HashMap headerMap = new HashMap();
                        headerMap.put("Authorization", Credentials.basic("user", mElasticSearchPassword));

                        String searchString = "";

                        if(!mSearchText.equals("")){
                            searchString = searchString + mSearchText.getText().toString() + "*";
                        }
                        if(!mPrefCountry.equals("")){
                            searchString = searchString + " country:" + mPrefCountry;
                        }

                        Call call = searchAPI.search(headerMap, "AND", searchString);

                        call.enqueue(new Callback() {
                            @Override
                            public void onResponse(Call call, Response response) {

                                HitsList hitsList = new HitsList();
                                String jsonResponse = "";
                                try{
                                    Log.d(TAG, "onResponse: server response: " + response.toString());

                                    if(response.isSuccessful()){
                                        hitsList = response.body().getHits();
                                    }else{
                                        jsonResponse = response.errorBody().string();
                                    }

                                    Log.d(TAG, "onResponse: hits: " + hitsList);

                                    for(int i = 0; i  call, Throwable t) {
                                Log.e(TAG, "onFailure: " + t.getMessage() );
                                Toast.makeText(getActivity(), "search failed", Toast.LENGTH_SHORT).show();
                            }
                        });
                    }

                    return false;
                }

e.g. the code renders the ff query which shows the available cities with NEW in its name inside the country US :

_search?default_operator=AND&q=new*+country:Us

but what im trying to achieve is something like this :

_search?default_operator=AND&q=new*+country:Us||Canada

that should result in showing all cities with NEW in its name inside US OR CANADA.

but || doesnt seem to work, so im asking for the correct Retrofit OR operator, or something that can help me achieve my goal.

What's the question? What problem you're facing with current code posted here as minimal reproducible example? Please elaborate. And also a sample URL that you're trying to access would be helpful to understand the problem. — Shashanth

Found the answer :

| signifies OR operation

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-simple-query-string-query.html

But it doesnt work in queries, so to achieve my goal I need to turn | into OR (with spaces before and after)

_search?default_operator=AND&q=new*+country:(Us OR Canada)
