What about escaping preexisting backslashes in the query string? I suppose
that would have to be done first.
> Jena Text Elastic Search Does not perform proper date comparison during query
> -----------------------------------------------------------------------------
>
> Key: JENA-1532
> URL: https://issues.apache.org/jira/browse/JENA-1532
> Project: Apache Jena
> Issue Type: Bug
> Components: Text
> Affects Versions: Jena 3.7.0
> Reporter: Anuj Kumar
> Priority: Major
>
> Jena Text Elastic Search is an implementation of the text query capability of
> Jena to perform text based searching and Filtering of data. It uses [Query
> String
> Query|https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html]
> capability of elastic search to perform searches.
> We found a bug in the implementation where searching on date values does not
> work properly. For example, if we have a following text query:
> {code:java}
> SELECT ?s { ?s text:query ('2016-12-01T15:31:10-05:00') ;{code}
> then the implementation threw exception because there are unescaped ":"
> (colon) in the value. Since ":" is a reserved character in the Query String
> Query capability of Elastic search, we have to escape the character.
