# Combined Entities

In addition to the entities described in the Eduction Grammar Reference, the IDOL PII Package includes grammar files that contain "combined" entities. These files are named `combined_*.ecr` (or `combined_*_cjkvt.ecr` for Japan) and the entities match addresses, dates, driving license numbers, and so on, from multiple countries.

- The entities that end in `/all` match data for any supported non-CJKVT country or language.
- The entities that end in `/all_cjkvt` match data for any supported CJKVT country.
- The entities that end in `/gdpr` match data for any supported country or language subject to GDPR.

For example:

- Using `pii/address/all` from `combined_address.ecr` matches a postal address from any non-CJKVT country. This is similar to using the `address.ecr` grammar file and extracting `pii/address/??`.
- Using `pii/address/gdpr` from `combined_address.ecr` matches a postal address from any country subject to GDPR. This is similar to using the `address.ecr` grammar file and extracting `gdpr/address/??`.
- Using `pii/date/dob/context/all` from `combined_date.ecr` matches a date of birth written numerically or using words in any language. This is similar to using the `date.ecr` grammar file and extracting `pii/date/dob/context/???`.

The combined (`/all`, `/all_cjkvt` and `/gdpr`) entities provide a significant improvement in processing speed when you extract matches for all countries or languages.

You must run the script `pii_postprocessing.lua` as a post-processing task (see Configure Post Processing). Running the script ensures that the entity names returned by Eduction contain the relevant country code or language code. For example, if a UK postal address is found, the entity name in the returned match is still `pii/address/gb`, and not `pii/address/all`.

The combined grammar files might produce fewer matches, because (by default) only a single match is returned in cases where the same characters in the input text would match multiple countries or languages.

TIP: If you need all matches, you can turn on the `AllowMultipleResults` configuration option. This option slows down the matching process because it does not stop after a single match, but is generally still faster than using the individual grammars.
