# Combined Entities

In addition to the entities described in the PCI grammar set, the Named Entity Recognition Grammars Package includes grammar files that contain "combined" entities. These files are named `combined_*.ecr` (or `combined_*_cjkvt.ecr` for Japan) and the entities match names 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.

For example:

- Using `pii/names/all` from `combined_names.ecr` matches a name from any non-CJKVT country. This is similar to using the `name.ecr` grammar file and extracting `pii/name/??`.

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

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.

File | Entity
--- | ---
combined_name.ecr | pii/name/all
combined_name_cjkvt.ecr | pii/name/all_cjkvt
pii/name/latin/all_cjkvt
pii/name/cjkvt/all_cjkvt
