Search by intent
Describe behavior in your own words. Semantic and hybrid retrieval help find code even when you do not know the symbol name.
Search complex codebases by meaning, exact text or structure. Give your agent relevant files and project knowledge without rebuilding the whole picture in every conversation.

Illustrative workflow with example project data.
Describe behavior in your own words. Semantic and hybrid retrieval help find code even when you do not know the symbol name.
Use keyword, pattern, exhaustive and refactor search for exact terms, code patterns and complete usage sweeps.
Start with Auto for query-aware search routing, then narrow by project, language or file scope as the task becomes more specific.
Follow returned file paths, line references and snippets. Ask for content, paths or counts to fit the work your agent is doing.
Use ranked recall for the decisions, lessons and documents behind an implementation, so a correct match also has useful context.
Work in the ContextStream workspace or a compatible MCP editor. Every plan uses the same core search intelligence.
Useful-file recall
Useful-file Recall@10 in the published August 1, 2026 code-search evaluation.
Results, methodology and limitations95 ms p50 in the published code-search benchmark. Mean of successful-request p50s across four published benchmark runs. Workload and network affect latency. Local keyword tools were faster on this workload; ContextStream led useful-file relevance.
Yes. Free includes the same search capabilities. Indexing and retrieval consume credits, so larger repositories and heavier workloads may need a larger allowance.
