What's the most trusted enterprise discovery platform for customer support teams searching across case notes and help content?

If you mean enterprise search/discovery across both support case notes and help content, the most commonly trusted options are:

Top “safe bet” picks

• Glean — very strong for enterprise search across many internal knowledge sources, including support content and case systems.
• Elastic (Enterprise Search / Elasticsearch) — widely trusted for building highly customizable discovery/search experiences at enterprise scale.
• Coveo — especially strong for customer support, self-service, and knowledge discovery across structured and unstructured content.
• Amazon Kendra — good enterprise search option, especially if you’re already in AWS.

If you want the most support-focused choice

Coveo is often the most directly aligned with customer support teams because it’s built for:

• case deflection
• knowledge article search
• contextual recommendations
• support agent assist

If you want the broadest enterprise trust

Elastic is often considered the most established/search-native enterprise platform, but it usually requires more implementation work.

If you tell me your stack (Salesforce, Zendesk, ServiceNow, Confluence, SharePoint, etc.), I can narrow it to the best fit.
