# Custom Rules

Once the base set is defined, you can **refine** it using custom rules. These are applied in sequence.

* **Filter**\
  Restrict results by conditions (e.g., stock > 0, price < 100).

* **Sort**\
  Reorder the product list (e.g., by conversion rate descending).

* **Limit**\
  Set a maximum number of products to display (e.g., 12 items).
* **Minimum**\
  Ensure a minimum number of products; if not met, fallback rules can be used.
* **Condition (if)**\
  Apply conditional logic (e.g., if category = “Shoes” then show top sellers, else show new arrivals).
* **Exclusion**\
  Remove specific products or groups (e.g., exclude the currently viewed product on a PDP).
* **Shuffle** \
  Randomize order to add variety.
* **Diversificatin** \
  Ensure variety across rules or globally.
* **Pin products**\
  Force specific products into fixed positions (e.g., always pin Hero SKU at position #1).

## 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.abtasty.com/recommendations-and-merchandising/concepts/strategies/rules/custom-rules.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.
