Log Search vs Log Explore: Two Patterns, Two Tools

Search is for known questions; explore is for unknown ones. The patterns that make each fast.

Known query: 'find all errors with code X.' Indexed; sub-second.

Index the high-cardinality fields you query often. Drop the rest.

Explore

Open-ended: 'what was happening before this incident?' Cannot pre-index for unknown queries.

Aggregations help: top fields, top values. Helps the engineer build the right query.

Tool support

Search-first tools: Loki, Splunk. Explore-first: Honeycomb.

Many teams use both for different access patterns.
