Dokumen ini menjelaskan cara menggunakan kemampuan penelusuran semantik berbasis project yang ditawarkan oleh Penelusuran Katalog Universal Dataplex.
Penelusuran semantik, yang didukung oleh Gemini, menyederhanakan penemuan data tanpa memerlukan sintaksis penelusuran yang rumit. Layanan ini mendukung kueri bahasa alami, sehingga Anda dapat menelusuri resource menggunakan bahasa sehari-hari. Hal ini meningkatkan aksesibilitas bagi pengguna dengan berbagai tingkat keahlian teknis.
Mirip dengan penelusuran kata kunci, penelusuran semantik menekankan penemuan resource dengan menganalisis metadata yang terkait dengan resource dalam organisasi.
Penelusuran semantik mengandalkan metadata teknis untuk penemuan data. API ini juga mendukung metadata yang ditentukan pengguna, seperti aspek. Penelusuran semantik
berfokus pada peningkatan perolehan, bukan presisi.

This enhances\naccessibility for users with varying levels of technical expertise.\n\nSimilar to keyword search, semantic search emphasizes the discovery of resources\nby analyzing the metadata associated with the resources within an organization.\nSemantic search relies on technical metadata for data discovery. It also\nsupports user-defined metadata, such as\n[aspects](/dataplex/docs/enrich-entries-metadata#aspects). Semantic search\nfocuses on enhancing recall rather than precision.\n\nPricing\n-------\n\nSemantic search in Dataplex Universal Catalog is offered at no charge during\nPreview.\n\nDuring Preview, share your feedback and suggestions with the\nDataplex Universal Catalog team using the email address\n`dataplex-semantic-search-feedback@google.com`.\n\nRequired roles\n--------------\n\nWhen you search for resources in Dataplex Universal Catalog using natural language,\nDataplex Universal Catalog automatically and seamlessly applies the same\n[permissions you have for keyword search](/dataplex/docs/search-assets#required-roles).\n\nSearch for resources using semantic search\n------------------------------------------\n\n### Console\n\n1.
