631631### Session search limit
632632 
633An interactive terminal session can make 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 needs more searches, the notice tells it to ask you to raise the limit.
633An interactive terminal session has a limit of 200 WebSearch calls. Searches from the main conversation and from [subagents](/docs/en/sub-agents), such as a parallel research fan-out, count against the same limit. The limit requires Claude Code v2.1.212 or later.

635Set 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. An interactive terminal session's limit refills at about 100 calls per hour, and [`CLAUDE_CODE_WEB_SEARCH_REFILLS_PER_HOUR`](/docs/en/env-vars#variables) sets the rate. 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.
635While a session is at the limit, searches appear in the conversation as calls that did nothing. Claude gets a notice telling it to continue with the information it already gathered and, if it needs more searches, to ask you to raise the limit.

637To get more searches, raise the cap, wait for the limit to refill, or start a new conversation:
638 
639* **Raise the cap**: set the [`CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION`](/docs/en/env-vars#variables) environment variable to a positive whole number, such as `500`. The cap can be raised but not turned off.
640* **Wait for the refill**: on Claude Code v2.1.290 or later, an interactive terminal session's limit refills at about 100 calls per hour. To change the rate, set [`CLAUDE_CODE_WEB_SEARCH_REFILLS_PER_HOUR`](/docs/en/env-vars#variables) to a number of calls per hour, such as `50`.
641* **Start a new conversation**: running [`/clear`](/docs/en/commands#all-commands) at the Claude Code prompt also resets the count. If work that can still spawn subagents survives the clear, such as a running workflow, the count carries over instead.
