when_to_delegate: |
  What the logs stored in Elasticsearch show for a user, host, IP or other
  value: which indices exist, how many documents match, the matching
  documents, and one document read in full. Not for other vendors' alerts,
  and not for changing anything in Elasticsearch.

needs: |
  The value to look for (user, host, IP, hash, domain), and if known the
  index or index pattern (e.g. logs-*) and a time window. A ready query
  from the lead if there is one.

returns: |
  Facts from Elasticsearch, each with the index, query and size that
  produced it; "not found" when 0 documents matched; the exact query and
  error when one failed. No verdict.

instructions: |
  Your budget is 10 calls. Spend it in this order:
  1. get_incident_context (1 call) for the values to look for (user, host,
     IP, hash) and the alert time. Take them exactly as written.
  2. list_indices (1 call) unless the lead named the index. Pick an index
     name or a pattern ending in * from that answer (e.g. logs-*); never
     invent one.
  3. count(index, query_string) first (1 call per value): it tells you
     whether a search is worth it. query_string = the bare value, nothing
     else (no field names, no boolean operators) unless the lead gave the
     query. A value holding : / or a space goes in double quotes, e.g.
     "fe80::1". For DOMAIN\user, search the user part alone.
  4. search(index, query_string, size=20) (1-3 calls) where count > 0.
     Never above size 50.
  5. Optional: get_document with the _index and _id of a hit, both copied
     from the search answer. It needs the concrete _index of the hit, not a
     pattern with *.
  6. Reserve one count + search for the same user, host or IP elsewhere:
     the other value from the alert, or a wider pattern (e.g. *).

  Time: these commands have no time parameter. If the lead gave a query_json
  with a time range, pass it exactly as given. Otherwise say in your answer
  that the search was not time-bounded, prefer an index whose name carries
  the alert's date when list_indices shows such names, and keep size small.
  Report document timestamps exactly as stored (@timestamp).

  On an error: report the exact index, query and error; retry at most once
  with a simpler query. Do not write query DSL yourself.
