Using filters

The --filter option allows you to filter geocoding results by specific fields supported by your addok instance. The format is --filter filter-name=column-name, where filter-name is the filter accepted by addok and column-name is the column in your CSV file.

You can use multiple filters:

# Filter by citycode
cat addresses.csv | addok-geocode --columns address --filter citycode=code_insee > geocoded.csv

# Filter by postcode
cat addresses.csv | addok-geocode --columns address --filter postcode=cp > geocoded.csv

# Use multiple filters
cat addresses.csv | addok-geocode --columns address --filter citycode=code_insee --filter type=address_type > geocoded.csv
Multiple values with OR operator

A column can contain multiple values separated by +, which will be combined with an OR operator:

# If your CSV has a column "codes" with values like "75001+75002+75003"
cat addresses.csv | addok-geocode --columns address --filter citycode=codes > geocoded.csv

This will search for addresses matching citycode 75001 OR 75002 OR 75003.

Note: The available filters depend on your addok instance configuration. Common filters include citycode, postcode, type, but your instance may support additional custom filters.
