# 8. Rank filter
You can also filter the NFTs you want to see using their ranking. To display every listed NFT in the top 100, see below
 
For Scalp ranking calculation we use the same algorithm as Moonrank.
{% hint style="danger" %}
Our ranking is statistical and based on attributes from the NFTs of the whole collection. It normally matches Moonrank and SolRarity ranking. There are some exceptions when project owners want a different ranking (example HowRare.is) and they also address the aforementioned ranking platforms to also update accordingly. Unfortunately we don't know about this so we can't update.
**Rank is always calculated but not always displayed.** For collections that are unrevealed, **we try to hide the ranking** as it's not relevant. This is the case now for collections that only have 1 attribute and the same value for that attribute.\
There are cases when NFT's have for example 3 attributes, even thought 2 have the same values for every NFT. Ranking is not final but not hidden either. When revealed, the collection will have totally different attributes.
Be careful, for unrevealed collections, Scalp rank and any other rank will not be accurate until mint finish and collection reveal.
If you know that a collection has been fully revealed, you can trigger a rescann using button and the steps in [**Report an issue with the collection**](/troubleshooting/report-an-issue-with-the-collection.md)**.**

## 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://docs.scalp-empire.com/collection-analytics-and-sniping-page/8.-rank-filter.md?ask=&goal=
```
`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.
