Sometimes one applicant submits twice, or two applications describe the same project under
slightly different names. Each grant round has a `Duplicates` tab that groups these possible
duplicates so you can decide which one to keep. `Grant` and `Application` are your organisation's
own terms if you've renamed them.

## Before you start

- You need `Can access Funding Applications` to see the tab and act on its groups.
- To change the round's duplicate detection settings, you also need `Can access Grants`.

## Duplicate detection settings

Open the round and select the `Duplicates` tab. `Duplicate detection` at the top holds four
settings for this round:

- `Same applicant in this Grant` — on by default. A second submission from the same applicant is
  grouped with their first as soon as it arrives.
- `Similar names` — applications whose titles or applicant names read alike are grouped when you
  scan.
- `Similarity threshold (%)` — from 50% to 100%, 85% by default. Pairs at least this alike are
  grouped.
- `Show duplicate flag to assessors` — off by default. When it's on, assessors see
  `Possible duplicate` on the application, and nothing about the other one.

Select `Save detection settings`. If someone else saved the settings first, Backed says so and
shows their version.

## Scan for duplicates

Select `Scan for duplicates`. The scan runs in the background and new groups appear on the tab as
it finds them. A large round can take a few minutes; select `Refresh` to look again. A scan groups
up to 5,000 similar pairs at a time, the most alike first, so in a very large round scan again to
continue where it stopped.

## Work through the groups

`Show` lists the `Open` groups first. Choose `Resolved`, `Dismissed` or `All groups` to see the
others. Each group shows why it was raised (`Same applicant`, or `Similar names` with the
similarity), when it was found, and each application's number, title, applicant, similarity and
role: `Candidate`, `Primary` or `Archived as duplicate`.

- **Keep one.** Choose the application to keep, then select `Mark primary`. If you haven't chosen
  one, Backed asks you to. The others are archived as duplicates: they leave the default
  applications lists and are left out of assessment. Their applicants see no change.
- **Not duplicates.** Select `Dismiss` and confirm. Every application stays as it is, and no later
  scan groups these pairs again.
- **Undo an archive.** Select `Restore` beside an archived application. Restoring one reopens its
  group: the primary becomes a candidate again, and any other archived application stays archived
  until you mark a primary again.

If someone else resolved or dismissed the group first, Backed says so and shows where it stands.

## Possible duplicate on lists and applications

An application in an open group shows `Possible duplicate` on its page, with
`Review on the Duplicates tab`. An archived one shows `Archived as duplicate` and the day it was
archived. In the applications lists, add the `Duplicate` column under `Columns` to see the same
marks. Archived duplicates are hidden from the lists unless you choose them under
`Archived duplicates` in `Filters`.
