# Customize Stop Lists

The IDOL PII Package post-processing script (see Configure Post Processing) uses stop lists to discard matches that are likely to be false positives. You can add entries to the stop lists, or remove entries, by modifying the following files.

- `scripts/address_stoplist.lua` contains a list of common words that are likely to indicate a false positive when returned as the `STREET` or `CITY` component of an address match.
- `scripts/names_stoplist.lua` contains two stop lists to discard names. In the first stop list, each component is plausible but the entire match is likely to be a false positive, for example "Christian Church" or "Norman Conquest". The second stop list contains common words that are likely to indicate a false positive when returned as either the `FORENAME` or `SURNAME` component of a name match. The stop lists in this file can be customized such that a name can be considered a false positive in one country but not another.
