This query combines two main conditions with an implicit AND. The first condition, env:dev, filters for traces tagged with the development environment. The second condition, (@http.method:POST OR @http.method:GET), is a grouped clause that uses an explicit OR to find traces containing a span with an HTTP method of either POST or GET. The query returns traces that satisfy both the environment and the method conditions.

B. The space between env:dev and the parenthetical group acts as an implicit AND, not an OR.

C. The query explicitly searches for traces tagged with env:dev; it does not negate or exclude this tag.

D. The OR operator requires the trace to match one of the conditions (POST or GET), not both simultaneously.

1. Datadog Documentation, "Search for Traces". Section: "Search Syntax". States: "Use boolean operators AND, OR, and NOT to create your query." and "Use parentheses to group boolean operators." This confirms the logic for grouping and the OR operator.

2. Datadog Documentation, "Search for Traces". Section: "Search Syntax". Also confirms that a space between terms acts as an implicit AND, connecting env:dev to the grouped condition.

3. Datadog Documentation, "Standard Attributes". This page lists http.method as a standard attribute available for searching on spans.
