zendesk ticket from customer below - is there existing functionality for this and it is simply not documented?
The method Query.setKey( String ) converts strings consisting of digits into numbers instead of keeping the format a string. This can be seen by inspecting the Query object after running setKey( "300" ) (or any other all digit string). The internal association is ?key=300. For example, setKey( "Hey" ) yields ?key="Hey".
The issue here is that we have data stored in JSON documents where the data portion is treated as a string, but it is all digits. So, a query for setKey( "300" ) fails to match fields that contain "300", because the query is ultimately if ( 300 == "300" ).
There should be two versions of setKey(), one for strings and one for number types.
I was unable to find any documentation regarding this particular case, so I assumed it is not an expected issue.
The problem is inside of the Query class. In getArg(), the check for isJsonObject() returns true for stringified numbers, and the resulting key/value does not contain quotes. The result now is
We want the output of the query object to be
based on the input type (String or number). As of now, it makes that determination for us, which is incorrect.
which is impossible given the current implementation.
