Frequently Asked Questions

What’s the difference between Vertex AI Search and Vertex AI Agent Builder?
Vertex AI Search focuses on retrieving the best documents or passages from your content (web pages, PDFs, knowledge bases, etc.) using semantic understanding and relevance ranking. Vertex AI Agent Builder is used to create conversational agents that can call tools, follow workflows, and use retrieval (often via Vertex AI Search) to answer questions. In practice, Vertex AI Search is often the retrieval layer, while Agent Builder is the conversational and orchestration layer.
When should I use Vertex AI Search instead of building search on OpenSearch/Elasticsearch?
Use Vertex AI Search when you want a managed, Google-quality enterprise search experience with built-in semantic retrieval and faster time-to-value, especially for RAG-style applications and site/app search. Consider OpenSearch/Elasticsearch when you need deep low-level control over indexing, custom analyzers, cluster operations, or you already run and tune search infrastructure and want maximum flexibility.
How much does Vertex AI Search cost?
Pricing depends on factors like the edition/features you use, the number of documents indexed, query volume, and any generative AI/RAG features (which may add model inference costs). You should estimate cost by mapping expected indexing size and monthly queries, then include any additional charges for data ingestion, storage, and LLM usage if you generate answers. For exact numbers, use the current Google Cloud pricing page and the Google Cloud Pricing Calculator for your region and workload.
