How to implement search dynamically with NativeSearchQueryBuilder()?

if userId is null ,I want to remove .withQuery(QueryBuilders.matchQuery("createdBy",userId)) this condition, how can I implement search dynamically according to my passing parameters.

 public <T> List<T> search(String index, String type, String tenantId ,String userId, String queryString, Class<T> clzz){
    log.debug("==========search==========");
    String allField = "_all";
    MultiMatchQueryBuilder multiMatchQueryBuilder = QueryBuilders.multiMatchQuery(queryString, allField);

    SearchQuery searchQuery = new NativeSearchQueryBuilder()
            .withIndices(index)
            .withTypes(type)
            .withQuery(multiMatchQueryBuilder)
            .withQuery(QueryBuilders.matchQuery("tenantId",tenantId))
            .withQuery(QueryBuilders.matchQuery("createdBy",userId))
            .build();
    List<T> list =
            operations.queryForPage(searchQuery,clzz).getContent();
    return list;
}

Right, matchQuery does not accept null value and throws:

java.lang.IllegalArgumentException: [match] requires query value

NativeSearchQueryBuilder is an object like any other so you can build it after some additional preparation. Probably not the prettiest, but will do what you want:

NativeSearchQueryBuilder nativeSearch = new NativeSearchQueryBuilder()
    .withIndices(index)
    .withTypes(type)
    .withQuery(multiMatchQueryBuilder)
    .withQuery(QueryBuilders.matchQuery("tenantId", tenantId));

if (userId != null) {
    nativeSearch.withQuery(QueryBuilders.matchQuery("createdBy", userId));
}

SearchQuery searchQuery = nativeSearch.build();
