Meilisearch v1.54 dynamic search rules scale action weight required default weight omitted "scale"
💡 Result:
In **Meilisearch v1.54.0**, `scale` is an array of scale actions, and **each action requires a `weight`**—a nonnegative number. The release notes do not specify a default weight, so don’t omit it; provide one explicitly. ([newreleases.io](https://newreleases.io/project/github/meilisearch/meilisearch/release/v1.54.0?utm_source=openai))
```json
{
"actions": {
"scale": [
{ "filter": "availability = discontinued", "weight": 0 }
]
}
}
```
A weight above `1` boosts, below `1` demotes, and `0` hides matching documents unless they are pinned. ([newreleases.io](https://newreleases.io/project/github/meilisearch/meilisearch/release/v1.54.0?utm_source=openai))

Meilisearch v1.54 API dynamic search rules scale action weight required default value weight omitted official docs source
💡 Result:
**`weight` is required for each `scale` action; the official v1.54 source does not specify a default when it’s omitted.** The v1.54 announcement describes `weight` as the scale factor and explains its effects: above `1.0` boosts, below `1.0` demotes, and `0.0` hides selected documents. It does not say that `weight` may be omitted or define an omitted-value default. ([meilisearch.com](https://www.meilisearch.com/blog/september-2026-updates?utm_source=openai))
So don’t rely on an implicit default—include `weight` explicitly in every `scale` action. The official API reference wasn’t accessible in the retrieved sources, so I can’t confirm the exact validation error for omission. The announcement does establish that the feature is available via the API in v1.54. ([meilisearch.com](https://www.meilisearch.com/blog/september-2026-updates?utm_source=openai))

Make Weight nullable, or document it as required.
Meilisearch v1.54 requires weight for each scale action. If a caller omits it, DSRScale.Weight defaults to 0 and the client serializes that value. The server then treats it as an intentional zero weight, which hides the selected documents, rather than rejecting a missing field.
Suggested fix

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
