O.query()
Constructs a object implementing the StoreQuery interface.
There are two options for calling it:
function O.query()
Returns a blank StoreQuery object, ready for the query to be generated programmatically.
function O.query(string)
Returns a StoreQuery object generated by parsing the string as a query, exactly the same as a query in the Haplo user interface.
See the in-application help for details on the query syntax.
