在Haskell中實現搜索算法和排序算法通常通過函數式編程的方式來實現。以下是一些常見的搜索算法和排序算法的Haskell實現示例：
linearSearch :: Eq a => a -> [a] -> Maybe Int
linearSearch _ [] = Nothing
linearSearch x (y:ys)
| x == y = Just 0
| otherwise = fmap (+1) (linearSearch x ys)
binarySearch :: Ord a => a -> [a] -> Maybe Int
binarySearch _ [] = Nothing
binarySearch x xs = binarySearch' x xs 0 (length xs - 1)
binarySearch' :: Ord a => a -> [a] -> Int -> Int -> Maybe Int
binarySearch' _ _ lo hi | lo > hi = Nothing
binarySearch' x xs lo hi
| x == xs !! mid = Just mid
| x < xs !! mid = binarySearch' x xs lo (mid - 1)
| otherwise = binarySearch' x xs (mid + 1) hi
where mid = (lo + hi) `div` 2
bubbleSort :: Ord a => [a] -> [a]
bubbleSort xs = foldr (\x sorted -> bubble x sorted) xs [1..length xs-1]
bubble :: Ord a => a -> [a] -> [a]
bubble x [] = [x]
bubble x (y:ys)
| x < y = x:y:ys
| otherwise = y : bubble x ys
以上是一些簡單的搜索算法和排序算法的Haskell實現示例。為了優化這些算法，可以使用惰性計算、尾遞歸優化、模式匹配等技術。另外，還可以考慮使用更高效的數據結構，如數組和向量，來提高算法的性能。
