Требует ли модуль text-query-es «ограничения» в синтаксисе SPARQL?

Я хотел переключиться наasticsearch (6.4.2), но не смог заставить его работать с выпущенной версией Fuseki (3.12.0), просто включив jar-файл jena-text-es с java -cp. Поэтому я создал Fuseki после добавления его в качестве зависимости в файлах pom.xml в jena-fuseki-core и jena-fuseki-webapp.

Это сработало, но я столкнулся с некоторыми проблемами при попытке запустить text: querySPARQL-запросы без передачи аргумента limit.

Документация перечисляет его как необязательный входной аргумент, но когда я его не включаю, он возвращает параметр [size]не может быть отрицательным, найдено [-1] (# 500) сообщение об ошибке. Требуется ли это в реализации es?

Я попытался изменить версию Fuseki на 3.10.0 (версия указана в таблице совместимости), но все равно выдает ту же ошибку.

(Для следующих примеров запросов я загрузил data-es.ttl в график по умолчанию.)

Следующий запрос возвращает мне ожидаемый результат : 

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX text: <http://jena.apache.org/text#>

SELECT ?subject ?object
WHERE {
?subject text:query ('Whatever' 1).
?subject rdfs:label ?object .
}

, но следующее выдает вышеупомянутую ошибку : 

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX text: <http://jena.apache.org/text#>

SELECT ?subject ?object
WHERE {
?subject text:query ('Whatever').
?subject rdfs:label ?object .
}

Журналы Fuseki показывают следующее: 

[2019-10-18 14:27:56] Fuseki     INFO  [31] Query = PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>   PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>   PREFIX text: <http://jena.apache.
