I am facing above error in spring data elastic search . how to parse simple query string in query builder? my code is

final QueryBuilder searchquery = QueryBuilders.boolQuery()  
.should(QueryBuilders.simpleQueryStringQuery(text)  
.field("question")  
.lenient(true));

```
    final NativeSearchQuery build = new NativeSearchQueryBuilder().withQuery(searchquery)
            .withPageable(PageRequest.of(0, 5))
            .build();

    final List<FaqTranslationEntity> questions = this.elasticsearchTemplate.queryForList(build, FaqTranslationEntity.class);
```

Is the `text` encoded with UTF8?

Could you share it and share a sample project which reproduces the problem?

I can't tell without being able to see or reproduce what is happening.

You did not share the content of `text`.

Could you also share the output of:

```
GET /yourindexname/_search?q=text 

```

Where you replace `yourindexname` and `text`.
