Find every flow and block whose contents contain a keyword. Read-only. Searches message text and its translations, button labels and URLs, action names and configs, action input/output field paths and values, condition operands, trigger commands and payloads, custom-code files, and flow names and descriptions. A keyword matching a VARIABLE NAME also returns the blocks that reference that variable, which plain text search cannot do because blocks store variable ids, not names. truncated is true whenever a limit dropped something, and cappedBy names which: FLOW_LIMIT (more flows matched than limit), ROW_LIMIT (the 1000-match ceiling was hit; lower-ranked matches were not read), MATCHED_VARIABLES (the keyword matched more than 25 variable names — only the 25 closest, shortest name first, are resolved to the blocks that reference them, so blocks reading the others are MISSING), MATCHES_PER_FLOW (a flow lists at most 12 matches; its matchCount is the real number), MATCHES_PER_BLOCK (a block lists at most 3). A truncated answer is not proof that nothing else matches: narrow the keyword, or search the full variable name, before you rename or remove something on the strength of it. Use this instead of walking flows with get_flow_context when you know what the content says but not where it lives. Broadcast-backed flows and operation graphs are excluded — use list_broadcasts and the operations tools for those.
