ElasticSearch Java Client querying nested objects

Question

How do I convert this kind of query.

{
  \"query\": {
    \"nested\": {
      \"path\": \"consultations\",
      \"query\": {
        \"bool\": {
          \

The folowing Java code will generate your query

public NestedQueryBuilder nestedBoolQuery(final Map<String, String> propertyValues, final String nestedPath) {

    BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
    Iterator<String> iterator = propertyValues.keySet().iterator();

    while (iterator.hasNext()) {
        String propertyName = iterator.next();
        String propertValue = propertyValues.get(propertyName);
        MatchQueryBuilder matchQuery = QueryBuilders.matchQuery(propertyName, propertValue);
        boolQueryBuilder.must(matchQuery);
    }

    return QueryBuilders.nestedQuery(nestedPath, boolQueryBuilder);
}

The parameter propertyValues is:

Map<String, String> propertyValues = new HashMap<String, String>();
propertyValues.put("consultations.prescriptions", "alfuorism");
propertyValues.put("consultations.Diagnosis", "Fever");

The parameter nestedPath is:
