Frequently asked questions

How does Vectara work?

Vectara uses LLMs and neural networks to apply complete vector encoding for all indexed content and all queries, allowing for a high efficacy semantic response. Vectara combines native neural indexing for all content, statistical keyword algorithms, and re-rankers to maximize the relevance of results across a wide spectrum of queries and data classes.

Is there a free plan?

Yes, Vectara’s Growth plan is free with a defined query volume that resets every month and storage capacity allocation. Customers who need more queries and / or storage capacity can purchase additional capacity bundles on the Growth plan.

What are the use cases for Vectara?
  1. Web and application search for digital media, online retail, communities, and forums
  2. Product search in SaaS and enterprise applications
  3. Question and answer oriented search such as FAQ search, customer support agent assistance, and chatbots
  4. Documentation search
How is Vectara different from other search solutions?

Vectara has many core features in its Search-as-a-Service platform, and we have unique features that address limitations of current in-market systems.

Some of Vectara’s unique differentiators include:

  1. 100 % neural, LLM-powered search pipeline – encoding, retrieval, and reranking – that delivers a true semantic response for all indexed content and query types.
  2. API-first semantic search as a service platform that can be easily set up by any web or application developer in minutes without prior configuration, tuning, or optimization.
  3. Intelligent search that eliminates the need for synonyms, stop words, spelling correction, and stemming rules.
  4. Cross language search – search an index in a given language with queries from a different language.
  5. Operationalization of industry-leading neural network models for ultra-fast and cost-effective search.
