Declaration search

Search projects and Mathlib in one place.

Find source-pinned declarations outside Mathlib by name or constant. The same query runs through Loogle for genuine elaborated structural search over Mathlib.

Name"PFR_conjecture"ConstantSubmoduleMathlib shape_ * (_ ^ _)Conclusion|- tsum _ = _ * tsum _Non-linearReal.sqrt ?a * Real.sqrt ?a

Therefore projects

Use a constant such as Submodule or quote a declaration-name fragment. Results keep the exact project, commit, module, and full source.

Mathlib through Loogle

Use wildcards, repeated metavariables, conclusion filters, or combine filters with commas. Queries are elaborated by Loogle rather than approximated from text.
