# IndexNumbers

The `IndexNumbers` parameter specifies whether to index numeric and alphanumeric values.

- If you do not want to use numeric or alphanumeric values for querying at all, set `IndexNumbers` to `0`.

- To index all numeric terms, set `IndexNumbers` to `1`. This option might result in a large number of terms if your documents include many numeric terms.

- To index alphanumeric terms, but not purely numeric terms, you can set `IndexNumbers` to `2`.

You can also restrict the `IndexNumbers` setting for individual fields by setting up a field process. For example, if you generally want to index all numbers, but for certain fields you do not want to index any numbers, you can set up a field process to restrict the index numbers for some fields.

For example:

    [English]
    IndexNumbers=1

    ...

    [SetIndexNumbersFields]
    Property=IndexNumbersFields
    PropertyFieldCSVs=*/DRECONTENT

    [IndexNumbersFields]
    IndexNumberstype=True
    IndexNumbers=2

In this example, IDOL Server generally indexes all numbers in index fields, but in the `DRECONTENT` field, it indexes only numbers that occur as part of a word.
