[Meilisearch v1.51.0] Add filter condition to Dynamic Search Rules

[Strift]

Context

Meilisearch v1.51.0 introduces filter conditions for Dynamic Search Rules (DSR). It also introduces a new lastUpdatedAt field in DSR responses.

Objective

Update the SDK to support:

• The new filter activation condition in the conditions object of a DSR. The filter condition contains a values key whose value is a JSON object mapping facet names to their expected filter values.
• The new lastUpdatedAt field returned by GET /dynamic-search-rules/{:ruleUid} and POST /dynamic-search-rules.

  — API reference

Example of a DSR with a filter condition

// PATCH /dynamic-search-rules/test-filter
{
  "conditions": {
    "filter": {
      "values": {
        "color": "red",
        "category": "shirt"
      }
    }
  },
  "actions": [
    {
      "selector": {
        "indexUid": "products",
        "id": "123"
      },
      "action": { "type": "pin", "position": 1 }
    }
  ]
}

Tasks
