Vector Search
1 min read · Reviewed 17 Oct 2026
In short
Searching by meaning rather than by matching words.
In plain English
Finding material that means something similar to your query, instead of material containing the same words.
A real example
Searching your help pages for "my payment failed" and surfacing the article titled "Declined card troubleshooting", which shares no keywords.
Why it matters
It is what makes a knowledge base actually usable. Keyword search fails whenever the customer's words differ from yours, which is most of the time.
