# PreFilterMaxReturnedBytes

The maximum number of bytes that a pre-filter task can produce without a resulting Eduction match.

The pre-filter process generates windows with potential matches, based on your pre-filter criteria. Eduction runs matching on these windows as soon as the pre-filter generates them. `PreFilterMaxReturnedBytes` allows you to specify a threshold for the amount of data that the pre-filter can output without a subsequent match. This option allows you to more quickly reject documents that match the pre-filter but are unlikely to contain real matches.

When a match is found in a pre-filter window the counter is reset and another match must occur before the specified limit is reached, otherwise Eduction stops processing.

To turn off this pre-filter threshold, set `PreFilterMaxReturnedBytes` to 0 (unlimited).

Type: | Integer
Default: | 0 (unlimited)
Required: | No
Configuration Section: | Eduction
Example: | `PreFilterMaxReturnedBytes=1000000`
