-------------------------------------------

             Summary: Document what needs to be configured for an attribute to be available for projection
                 Key: ISPN-10256
                 URL: https://issues.jboss.org/browse/ISPN-10256
             Project: Infinispan
          Issue Type: Bug
          Components: Documentation-Query
    Affects Versions: 9.4.14.Final
            Reporter: Gustavo Lira e Silva


When we query something using containing grouping and aggregation functions we receive the exception bellow:

{noformat}
org.infinispan.objectfilter.ParsingException: ISPN014021: Queries containing grouping and aggregation functions must use projections.
{noformat}

The code used to receive this exception:

{code:java}
Query q = createQueryFromString("select count(u.something) from  User u where user.name = 'John' Group By u.name");
{code}

setProjections on QueryBuilder is deprecated and the information about how to use Projections using Query String is missing...

Also there is a TODO in http://infinispan.org/docs/stable/user_guide/user_guide.html#projections
