Queries on the GraphQL API give no results, if query string has spaces.

[Schi11er]

This is a known GraphQL provided problem.
How can this fixed?

Example:

query rev {
  findSubjects(input: {query: "Revisionsbauteil  Leitungsbau", pageSize: 100000}) {
    totalElements
    nodes {
        id
    }
  }
}

This query gives 0 results although the subject is in database.
