extensions:
  search:
    driver: "elasticsearch"           # "inmemory", "elasticsearch", "meilisearch", "typesense"
    url: "http://localhost:9200"
    hosts:                             # alternative to url for multi-node clusters
      - "http://node1:9200"
      - "http://node2:9200"
    username: "elastic"
    password: "changeme"
    apiKey: ""                         # used by Typesense

    # Connection settings
    maxConnections: 10
    maxIdleConnections: 5
    connectTimeout: "5s"
    requestTimeout: "30s"
    keepAlive: "30s"

    # Retry settings
    maxRetries: 3
    retryBackoff: "100ms"
    retryOnTimeout: true

    # Search defaults
    defaultLimit: 20
    maxLimit: 100
    defaultMinScore: 0.0
    enableHighlight: true
    enableFacets: true

    # Performance
    bulkSize: 1000
    flushInterval: "1s"
    enableCompression: false

    # TLS
    enableTLS: false
    tlsCertFile: ""
    tlsKeyFile: ""
    tlsCAFile: ""
    insecureSkipVerify: false

    # Observability
    enableMetrics: true
    enableTracing: true

The extension loads config from extensions.search first, falling back to search.

Programmatic Configuration02

ext := search.NewExtension(
    search.WithDriver("meilisearch"),
    search.WithURL("http://localhost:7700"),
    search.WithAPIKey("masterKey"),
    search.WithDefaultLimit(25),
)

Or provide a complete config:

ext := search.NewExtensionWithConfig(search.Config{
    Driver:   "elasticsearch",
    Hosts:    []string{"http://node1:9200", "http://node2:9200"},
    Username: "elastic",
    Password: "changeme",
})

Validation04

Config.Validate() checks:

Driver is one of inmemory, elasticsearch, meilisearch, typesense
Elasticsearch requires URL or Hosts
Meilisearch requires URL
Typesense requires URL or Hosts, plus APIKey
