# IndexNumbers1TruncateLength

The maximum length (in number of characters) that a purely numeric term can be. Purely numeric terms that are longer than this value are truncated.

For example, if you set `IndexNumbers1TruncateLength` to `5`, the term `1234567890` is truncated to `12345`, and the term `12345` is indexed. A query for the term `1234567890` returns documents that contain the term `12345`.

NOTE: If you set the value of `IndexNumbers1TruncateLength` to be higher than the value of TermSize, the TermSize restriction takes precedence.

Type: | Long
Default: | `0`
Required: | No
Configuration Section: | Server
Example: | `IndexNumbers1TruncateLength=4`
