In the rare occasions when you have files with more than a hundred fields and Alpha predicts too many match fields than the current process limitation, it will just show you the best 120 fields so that you can proceed with the setup smoothly.
To determine which fields are better, Alpha ranks them by:
- Confidence level as per the prediction model;
- If fields have the same confidence level, then the one that appears further to the left in the left hand side input file will take precedence, assuming they are more important.
You can of course review the predictions and continue finalising the configurations manually.
