# Duplicatenfilter

Duplicaatfilter vermindert herhaalde bedrijfsrecords.

## Beschermingslagen

* Duplicaten binnen de huidige zoekopdracht
* Duplicaten tussen categorieën
* Duplicaten gevonden in eerder opgeslagen zoekopdrachten

## Waarom de uiteindelijke resultaten lager kunnen zijn

Wanneer er al veel kandidaten bestaan in de lokale duplicaatindex, kan Geo Prospector onder de doelstelling eindigen in plaats van herhaalde records terug te geven.

## Operationeel advies

* Houd het filter ingeschakeld voor terugkerende campagnes.
* Maak een back-up van de lokale gegevensmap.
* Verwijder duplicaatgegevens niet terwijl de toepassing actief is.
* Gebruik alleen een schone projectstrategie wanneer u bewust een nieuwe marktscan nodig hebt.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://visi-digital-internasional.gitbook.io/geo-prospector/geo-prospector-nl/prospectiewerkstromen/duplicate-filter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
