Semantic Search

How vector search and hybrid search work to find information by meaning, not just keywords.

How Semantic Search Works

Traditional keyword search matches exact words — searching for "pricing" only finds entries containing the word "pricing." Semantic search is fundamentally different. It understands meaning. When you search for "how much do we charge," it finds entries about pricing, rates, fees, and costs — even if none of them contain the exact phrase you searched for. This works through vector embeddings, mathematical representations of meaning that allow the system to measure how semantically similar two pieces of text are.

Search in Practice

Semantic search sits behind most of what your AI employee does. When you ask a question, it searches your knowledge base for relevant information. When it drafts an email, it searches for the contact's details and recent interactions. When it prepares a proposal, it searches for your pricing and template preferences. You rarely need to explicitly "search" — it happens as part of handling your request.

Finding information by meaning

Semantic search understands what you mean.

You say:
What discount do we give to nonprofits?
Sarudo responds:
Based on your knowledge base, you offer a 25% discount on all services for registered nonprofit organizations. This was established in January 2026 as part of your social impact initiative. The discount applies to both setup fees and monthly subscriptions. I found this from your pricing policy document and a conversation from February where you confirmed it for a specific client.

Improving Search Quality

The quality of search results improves as your knowledge base grows and becomes more organized. You can improve search quality by being specific when storing knowledge (include context and details), using consistent terminology across your knowledge entries, categorizing knowledge appropriately, and periodically reviewing and updating outdated information. The more structured and detailed your knowledge base, the more accurate and useful search results will be.
