嚯嚯嚯嚯嚯嚯function searchKeys(searchParam: string): string[] {
const loweredSearchParam = searchParam.toLowerCase();
const keys: string[] = Object.keys(searchData).filter((key: string) => {
const keywords: string[] = searchData[key];
return keywords.some((keyword: string) => keyword.toLowerCase().includes(loweredSearchParam));
});
return keys;
