docs: Create an OQL query from the string parameter.
  In order to execute a query, an <code>OQLQuery</code> object must be created
  by calling <code>Implementation.newOQLQuery</code>, then calling the
  <code>create</code> method with the query string.
  The <code>create</code> method might throw <code>QueryInvalidException</code>
  if the query could not be compiled properly. Some implementations may not want
  to compile the query before <code>execute</code> is called. In this case
  <code>QueryInvalidException</code> is thrown when <code>execute</code> is called.
  @param	queryString	An OQL query.
  @exception	QueryInvalidException	The query syntax is invalid.
