Traditional Information Retrieval started with score-based ranking for search results using scores such as TF-IDF[1] or BM25[2]. As search engines got better, the scores they used started getting better. A lot of big search engines use a heuristic / score-based model for search ranking. Most famously, as recently as 2011, Google used a heuristic model for ranking in search[3] in spite of having a really strong in-house expertise in Machine Learning. As of October 2017, Wikipedia also used BM25 for search ranking, and experimented with using a ML-model, but the results were mixed[4].

Ranking search results using machine learned models has been explored for at least a couple of decades now. It has gained even more prominence with the popularity of Learning to Rank[5] techniques in the last decade or so. For example, Bing has been using Learning to Rank techniques to rank its search results at least from 2009[6].

This is a choice a lot of new and existing search engines have to make: Should they go for hand-tuned, score-based models or should they use machine learning for ranking search results.

Here are some of factors that matter and should go into your decision-making. Note that most of these points are generic enough to apply to any prediction/ranking problem and are not restricted strictly to search.

The mechanical advantage makes the work output greater than the work input.

The machine can put out force without having any force applied to it.

A large force can be exerted through a long distance to have a small force exerted through a short distance.

Due to using machine we can make our work easier
It also save most time
but it also cause pollution

I am not sure about answer
