Execute ANY OpenSearch DSL query and return synthesized results.

You have FULL FLEXIBILITY to build any query:

• Complex bool queries with must/should/filter/must_not

• has_parent, has_child, nested queries

• Any aggregations (terms, stats, date_histogram, scripted_metric, etc.)

• Script sorting, script fields, script filters

• Geo queries, range queries, wildcards, match, term, etc.

The proxy executes your query and returns COMPACT formatted output instead of raw JSON.

OUTPUT FORMATS:

• auto: Detects best format (default)

• table: Tabular format for multiple hits

• list: One-line-per-hit format

• summary: Just counts and aggregations

• compact_json: Minimal JSON (only _source, no metadata)

IMPORTANT: Build the full DSL query object as you normally would.

Quick document count with optional query filter. Lighter than full query.

Get index mapping to understand available fields. Returns compact field list.
