ChEMBL Search Molecules

Search molecules by name, ChEMBL ID, or other criteria. Supports filtering and pagination. Note: some text-based filters (especially `pref_name__contains`) may legitimately return zero results because `pref_name` coverage is incomplete and may not contain common drug names. For reliable retrieval, prefer ID-based filters like `molecule_chembl_id` or use `ChEMBL_get_molecule` when you already have a ChEMBL ID.
