Search tools cover three related jobs: search inside a website or app, enterprise search across a company's own scattered systems, and search APIs that developers embed. All three are being rewritten by AI retrieval, which changed the expectation from a list of blue links to a direct answer with sources. Relevance tuning and latency remain the things you actually buy.

Ordered by App Advisor rating. Nothing here is paid placement — see how we rate software.
Look at zero-result analytics during the trial. What your users search for and do not find is the most valuable output of any search tool.
For enterprise search, permission awareness is non-negotiable: results must respect the access rules of the source system, not a copied snapshot.
Model the pricing unit against growth — per-record pricing behaves very differently from per-query once your catalogue or traffic grows.

Enterprise search indexes the systems a company already uses — drive, email, wiki, tickets, CRM — and lets staff find and ask questions across all of them, returning only what each person is permitted to see.
For questions phrased in natural language, yes. For exact lookups — a part number, an invoice ID — keyword matching is still more reliable, which is why serious tools combine both.
Small sites often fit free tiers. Paid plans usually price per thousand records or per thousand queries, so the cost depends on catalogue size and traffic rather than seats.
