---------------------------------------
Any update on this, In olingo 4 how is possible to "decompose" left and right
into inner expression?
> Is grouping in $filter with "(" and ")" possible?

> Key: OLINGO-1120
> URL: https://issues.apache.org/jira/browse/OLINGO-1120
> Project: Olingo
> Issue Type: Question
> Components: odata4-server
> Affects Versions: (Java) V4 4.3.0
> Reporter: Werner Mueller
> Priority: Major
>
> I'm implementing an OData-server-application with Version v4.3.0 of Olingo.
> According to
> https://olingo.apache.org/doc/odata4/tutorials/sqo_f/tutorial_sqo_f.html
> I created an ExpressionVisitor
> to construct a valid JDBC/SQL-where constraint.
> I had a look to
> https://olingo.apache.org/doc/odata2/tutorials/Olingo_Tutorial_AdvancedRead_FilterVisitor.html
> also.
> My problem is with grouping.
> OData states that the Operators "(" and ")" should have the highest
> precedence (5.1.1.9 Operator Precedence,
> http://docs.oasis-open.org/odata/odata/v4.0/os/part2-url-conventions/odata-v4.0-os-part2-url-conventions.html)
> How can I handle grouping with the ExpressionVisitor?
> These are my urls for testing:
> http://localhost:8080/Odata.svc/SomeEnittySet?$filter=(id gt 5 or shortName
> ne 'xxx' or name eq 'test') or (name eq 'xxx' and id lt 567)
> and
> http://localhost:8080/Odata.svc/SomeEnittySet?$filter=(id gt 5 or shortName
> ne 'xxx' or name eq 'test') or name eq 'xxx' and id lt 567
