Which search engine I can choose among the Sphinx/Solr/Elasticsearch?

For better user experience, every business requires a search engine for an e-commerce site. The quick and relevant search result is the most important part of every search engine.

Nowadays, every user searches for their required product on the website and expects a relevant result. What happens if your search engine is unable to provide the relevant results? Will it abandon the site or will it try with different synonyms?

To resolve this issue, there are various open-source search engines available in the market but we're picking the best search engines among them.

First of all, each search engine has its own benefits and can be utilized according to the requirements. To choose a search engine, we must think about the following three things.

  1. Catalog size: Size of catalog in your store.
  2. Indexing: Search engine capacity to handle a real time search.
  3. Memory: Server also matters for search engines. Because it requires memory to perform the operation.

Let’s overview some search engines.

Elastic search:

  • Elasticsearch is currently at the top position among all the search engines. Elasticsearch has changed the performance limitations. It’s performance and relevance is much higher than all other search engines.
  • Elasticsearch also quickly updates the data and it's very important with real-time indexing.
  • When the size of the database increases, it's difficult to work with it but elastic search also scales up accordingly and it doesn't impact the search result.
  • When you have a large catalog of approximately 60k+ then only you can feel the actual performance impact of elastic search more than the other search engines.
  • Elasticsearch also consumes more memory so, your server should be with high configuration.


  • Solr stands at the second rank on the trending chart of search engines. It has its separate benefits from other search engines. If you want the functionality that your search engine can read the rich content like text, pdf documents then you must prefer the Solr search engine.
  • Solr stands at different positions because of its performance and features.
  • Solr has very great capabilities for faceted search. 
  • This search engine works best for the static data which are not frequently updating.


  • The next search engine on my list is Sphinx. Sphinx is a very popular and experienced search engine. This search engine has powerful capabilities for the layered navigations due to its expertise and experiences.
  • Sphinx search supports the high scalability but not as compared to the elastic search.
  • Sphinx search consumes very less memory than other search engines. When your server is not with the high configuration then you must prefer this search engine.

Here, we can't compare the above search engines because each has its individual feature which leads them in the market. Basically, When you have a very large catalog and high configured server then you must prefer the elastic search to see it's extraordinary capabilities. But if your catalog size is small then you can choose the Sphinx/Solr.

I hope you got a good understanding of the different kinds of Search Engines. Let me know your thoughts in the comment section. And if you have any query with this blog I will be happy to solve that. Thanks and cheers … :)
