Explore Vertex AI website search features, including Enterprise edition tools like extractive answers, image search, and advanced LLM capabilities for summaries.
There is a powerful feature in Google's Vertex Artificial Intelligence platform that lets you test and fine-tune AI models using your own website content. This system operates in a straightforward, four-step process: prepare, retrieve, signal, and serve.
To set up website search, you first need to enable Enterprise edition features. Doing this unlocks extractive answers pulled directly from your documents, along with image search and core generative answers. For even faster updates, lower latency, and search summaries, you can turn on advanced website indexing.
If you want to take it further, advanced Large Language Model features offer search summarization, follow-up questions, and advanced generative answers. You can test different models to see what works best for your specific needs, including various versions of Gemini Flash and Gemini Pro.
The platform also gives you deep control over the user experience. You can customize the tone, style, and language of the generative summaries, and choose whether to suggest related questions. To keep quality high, you can set the system to ignore adversarial queries and filter out low-relevance content. Just keep in mind that once you set everything up, your results will only become available after Google's datastore indexes your content.
Tharindu Gunawardana from Search Ministry has discovered a cool feature in Vertex AI:
Looks like we can now test and fine-tune AI Mode in Vertex AI > Vertex AI Mode, using our own website content. This also confirms the process of how AI Mode works (Simplified version )
Prepare > Retrieve > Signal > Serve
I’ll be investigating it and documenting my progress on this page.
