Elasticsearch ES|QL

Execute ES|QL queries against Elasticsearch: discover the schema, choose the right ES|QL feature for the task, generate the simplest correct query, and run it.

Environment Configuration

This skill executes Elasticsearch operations through the elastic CLI. If the elastic CLI is not installed, tell the user what it is needed for. Do not guess credentials, call the HTTP API directly, or attempt other workarounds.

This skill references operations in HTTP-shorthand form (e.g., GET /, GET /_cat/indices, GET /{index}/_mapping, GET /{index}/_settings/index.mode, POST /_query). The Operations table at the end of this document maps each shorthand to the equivalent elastic CLI command — always use the CLI rather than calling the HTTP API directly.

What is ES|QL?

ES|QL (Elasticsearch Query Language) is a piped query language for Elasticsearch. It is NOT the same as:

Elasticsearch Query DSL (JSON-based)
SQL
EQL (Event Query Language)

Prerequisite: ES|QL requires _source to be enabled on queried indices. Indices with _source disabled (e.g., "_source": { "enabled": false }) will cause ES|QL queries to fail.

Version Compatibility: ES|QL was introduced in 8.11 (tech preview) and became GA in 8.14. Features like LOOKUP JOIN (8.18+), MATCH (8.17+), and INLINE STATS (9.2+) were added in later versions. On pre-8.18 clusters, use ENRICH as a fallback for LOOKUP JOIN (see generation tips). INLINE STATS and counter-field RATE() have no fallback before 9.2. Check references/esql-version-history.md for feature availability by version.

Cluster Detection: Call GET / to determine the cluster type and version:

build_flavor: "serverless" — Elastic Cloud Serverless. version.number tracks the stack line under active development (next minor from main), so clients that only semver-compare may treat Serverless as “latest.” Do not use version.number to gate features: if build_flavor is "serverless", assume all GA and preview ES|QL features are available.

build_flavor: "default" — Stack (self-managed or Cloud-hosted). Use version.number for feature availability.

Snapshot builds have version.number like 9.4.0-SNAPSHOT. Strip the -SNAPSHOT suffix and use the major.minor for version checks. Snapshot builds include all features from that version plus potentially unreleased features from development — if a query fails with an unknown function/command, it may simply not have landed yet. Elastic employees commonly use snapshot builds for testing.

Process

Verify the connection and detect the deployment type. Call GET / first. This confirms connectivity and detects whether the deployment is a Serverless project (all features available) or a versioned cluster (features depend on version). The build_flavor field is the authoritative signal — if it equals "serverless", ignore the reported version number and use all ES|QL features freely. If the call fails, stop and point the user at the CLI configuration instructions rather than guessing endpoints or credentials.
Discover the schema (required — never guess index or field names). List candidate indices with GET /_cat/indices (pass a pattern to narrow), then fetch field types for the chosen index with GET /{index}/_mapping.

Always run schema discovery before generating queries. Index names and field names vary across deployments and cannot be reliably guessed. Even common-sounding data (e.g., "logs") may live in indices named logs-test, logs-app-*, or application_logs. Field names may use ECS dotted notation (source.ip, service.name) or flat custom names — the only way to know is to check.

Prefer simplicity: Query a single index unless the user explicitly asks for data across multiple sources. Do not combine indices with different schemas using COALESCE unless specifically requested — pick the single most relevant index for the question. When multiple indices contain similar data, prefer the one with the most complete schema for the task at hand.

Detect time series indices. Check the index mode with GET /{index}/_settings/index.mode. If it is time_series, use TS <data-stream> (not FROM), TBUCKET(interval) (not DATE_TRUNC), and wrap counter fields with SUM(RATE(...)). Read the full TS section in Generation Tips before writing any time series query. For TSDS indices on 9.4+, prefer the in-language discovery commands METRICS_INFO and TS_INFO (both GA) over inspecting mappings — they enumerate the metric catalogue and the dimension labels of each time series directly, and are run as ES|QL queries via POST /_query. Treat METRICS_INFO as authoritative for metric_type (counter//) and (, , for distribution metrics). Both must follow and must precede //. See :

Version availability: This section omits version annotations for readability. Check ES|QL Version History for feature availability by Elasticsearch version.

Basic Structure

FROM index-pattern
| WHERE condition
| EVAL new_field = expression
| STATS aggregation BY grouping
| SORT field DESC
| LIMIT n

Common Patterns

Filter and limit:

FROM logs-*
| WHERE @timestamp > NOW() - 24 hours AND level == "error"
| SORT @timestamp DESC
| LIMIT 100

Aggregate by time: For time series (TSDS) indices, prefer TS with TRANGE and TBUCKET over FROM + DATE_TRUNC (see the time series section below).

TS metrics-*
| WHERE TRANGE(7 days)
| STATS avg_cpu = AVG(cpu.percent) BY bucket = TBUCKET(1 hour)
| SORT bucket DESC

Top N with count:

FROM web-logs
| STATS count = COUNT(*) BY response.status_code
| SORT count DESC
| LIMIT 10

Text search (8.17+): Use MATCH as the default for full-text search instead of LIKE/RLIKE — it is significantly faster and supports relevance scoring. MATCH on a text field is usually sufficient on its own — do not add redundant keyword equality filters (e.g., category == "X") alongside MATCH unless the user explicitly requests filtering. Use QSTR only when you need advanced boolean logic, wildcards, or multi-field searches in a single expression. The first argument to MATCH must be one real field name — not a string listing several fields (e.g. "title,content") and not multiple field arguments; combine fields with MATCH(a, "q") OR MATCH(b, "q"). KQL is available from 8.18/9.0+. For content/document search use cases, follow the ES|QL Search Strategy. See ES|QL Search Reference for the full function guide.

## What is ES|QL?

ES|QL (Elasticsearch Query Language) is a piped query language for Elasticsearch. It is **NOT** the same as:

- Elasticsearch Query DSL (JSON-based)

`FROM index | WHERE condition | STATS aggregation BY field | SORT field | LIMIT n`

## Process

1. **Verify the connection and detect the deployment type.** Call `GET /` first. This confirms connectivity and detects
   whether the deployment is a Serverless project (all features available) or a versioned cluster (features depend on
   version). The `build_flavor` field is the authoritative signal — if it equals `"serverless"`, ignore the reported
   version number and use all ES|QL features freely. If the call fails, stop and point the user at the CLI configuration
   instructions rather than guessing endpoints or credentials.

2. **Discover the schema (required — never guess index or field names).** List candidate indices with
   `GET /_cat/indices` (pass a pattern to narrow), then fetch field types for the chosen index with
   `GET /{index}/_mapping`.

   Always run schema discovery before generating queries. Index names and field names vary across deployments and cannot
   be reliably guessed. Even common-sounding data (e.g., "logs") may live in indices named `logs-test`, `logs-app-*`, or
   `application_logs`. Field names may use ECS dotted notation (`source.ip`, `service.name`) or flat custom names — the
   only way to know is to check.

   **Prefer simplicity:** Query a single index unless the user explicitly asks for data across multiple sources. Do not
   combine indices with different schemas using `COALESCE` unless specifically requested — pick the single most relevant
   index for the question. When multiple indices contain similar data, prefer the one with the most complete schema for
   the task at hand.

   **Detect time series indices.** Check the index mode with `GET /{index}/_settings/index.mode`. If it is
   `time_series`, use `TS <data-stream>` (not `FROM`), `TBUCKET(interval)` (not `DATE_TRUNC`), and wrap counter fields
   with `SUM(RATE(...))`. Read the full TS section in [Generation Tips](references/generation-tips.md) before writing
   any time series query. For TSDS indices on 9.4+, prefer the in-language discovery commands `METRICS_INFO` and
   `TS_INFO` (both GA) over inspecting mappings — they enumerate the metric catalogue and the dimension labels of each
   time series directly, and are run as ES|QL queries via `POST /_query`. Treat `METRICS_INFO` as authoritative for
   `metric_type` (`counter`/`gauge`/`histogram`) and `field_type` (`histogram`, `tdigest`, `exponential_histogram` for
   distribution metrics). Both must follow `TS` and must precede `STATS`/`SORT`/`LIMIT`. See
   [Time Series Queries](references/time-series-queries.md#metric-and-time-series-discovery):

   ```esql
   TS metrics-tsds | METRICS_INFO | SORT metric_name
   TS metrics-tsds | TS_INFO | KEEP metric_name, dimensions | SORT metric_name
   ```

3. **Choose the right ES|QL feature for the task.** Before writing queries, match the user's intent to the most
   appropriate ES|QL feature. Prefer a single advanced query over multiple basic ones.
   - "find patterns," "categorize," "group similar messages" → `CATEGORIZE(field)`
   - "spike," "dip," "anomaly," "when did X change" → `CHANGE_POINT value ON key`
   - "trend over time," "time series" → `STATS ... BY BUCKET(@timestamp, interval)` or `TS` for TSDB
   - "PromQL", "Prometheus query/dashboard/alert", `sum by (instance) (...)`, label matchers like `{cluster="prod"}` →
     `PROMQL` source command (9.4+ preview); see [PROMQL Command](references/promql-command.md). Prefer `TS` for native
     ES|QL phrasing.
   - "search," "find documents matching" → `MATCH` (default), `QSTR` (advanced boolean), `KQL` (Kibana migration). For
     content/document relevance search, follow the [ES|QL Search Strategy](references/esql-search-strategy.md)
   - "count," "average," "breakdown" → `STATS` with aggregation functions
   - "approximate," "estimate," "rough numbers," "fast/cheap stats on huge data" → `SET approximation=true;` before a
     `STATS` query (GA in 9.5+/Serverless, preview in 9.4); see [Query Approximation](references/query-approximation.md)

4. **Read the references** before generating queries:
   - [Generation Tips](references/generation-tips.md) - key patterns (TS/TBUCKET/RATE, per-agg WHERE, LOOKUP JOIN,
     CIDR_MATCH), common templates, and ambiguity handling
   - [Time Series Queries](references/time-series-queries.md) - **read before any TS query**: inner/outer aggregation
     model, TBUCKET syntax, RATE constraints, histogram metrics
   - [PROMQL Command](references/promql-command.md) — **read before any PROMQL query**: options, output schema,
     limitations, and `PROMQL` vs `TS` decision matrix (9.4+ preview)
   - [ES|QL Complete Reference](references/esql-reference.md) - full syntax for all commands and functions
   - [ES|QL Search Strategy](references/esql-search-strategy.md) — for content/document relevance search (retrieve →
     fuse → rerank)
   - [ES|QL Search Reference](references/esql-search.md) — for full-text search function syntax (MATCH, QSTR, KQL,
     scoring)
   - [Query Approximation](references/query-approximation.md) — **read before using `SET approximation`**: output
     columns, sampling/confidence-level tuning, unsupported functions and patterns (GA in 9.5+/Serverless, preview in
     9.4)

5. **Generate the query** following ES|QL syntax. Prefer the **simplest query** that answers the question — do not add
   extra indices, fields, or transformations unless the user asks for them. Only include fields in `KEEP` that directly
   answer the question. Do not add extra filter conditions beyond what the user specified (e.g., don't add
   `OR level == "ERROR"` when the user just said "errors").
   - Start with `FROM index-pattern` (or `TS index-pattern` for time series indices)
   - Add `WHERE` for filtering (use `TRANGE` for time ranges on 9.3+)
   - Use `EVAL` for computed fields
   - Use `STATS ... BY` for aggregations
   - For time series metrics: `TS` with `SUM(RATE(...))` for counters, `AVG(...)` for gauges, standard aggregations
     (`SUM`, `AVG`, `PERCENTILE`, … — not `*_OVER_TIME`) for histogram metrics, and `TBUCKET(interval)` for time
     bucketing — see the TS section in [Generation Tips](references/generation-tips.md) and
     [Histogram Metrics](references/time-series-queries.md#histogram-metrics)
   - For detecting spikes, dips, or anomalies, use `CHANGE_POINT` after time-bucketed aggregation
   - Add `SORT` and `LIMIT` as needed

6. **Execute the query** with `POST /_query`. Request tabular (TSV) output for clean, decoration-free results that are
   easy to read and post-process.
