Count matching documents
countRead-only
Count documents matching an OpenSearch DSL query clause without returning the documents. Use it when you need just the match count, not the data.
Instructions
Count documents matching a DSL query clause, without returning the documents.
Use this instead of search_dsl when you only need the number of matches, not
the documents themselves. Note the query_dsl shape differs from search_dsl's —
the schema says how. Returns the raw OpenSearch _count response
({"count": N, ...}).
This tool takes no time arguments and applies no default window, so a
bare call counts everything the index still holds, which on any real
capture is millions of documents. Bound it with a range clause inside
query_dsl, use malcolm_search when you want a human-readable time range,
or arkime_sessions_summary when you want byte and packet totals beside
the count.
