562562### Session search limit
563563 
564A session can make at most 200 WebSearch calls, counted across the main conversation and every [subagent](/docs/en/sub-agents) it spawns, so searches made by parallel research fan-outs count against the same limit. The limit requires Claude Code v2.1.212 or later. When Claude reaches the limit, further calls return a notice telling Claude to continue with the information it already gathered, rather than an error that would invite a retry. You don't see the notice: a capped call appears in the conversation as a search that did nothing, and if Claude genuinely needs more searches, the notice tells it to ask you to raise the limit.

566566Set the [`CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION`](/docs/en/env-vars) environment variable to change the cap; it accepts a positive whole number, so the cap can be raised but not turned off. Running [`/clear`](/docs/en/commands#all-commands) resets the count. If work that can still spawn [subagents](/docs/en/sub-agents) survives the clear, such as a running workflow, the count carries over instead.
