Apache Lucene vs. OpenSearch

Apache Lucene is a perfect text search implementation where the heap space usage needs to be kept to its minimal. It also enables search based on various search fields and most importantly the search and index process can happen simultaneously. The only scenario where it might be less appropriate would be when the index size grows too big. We have witnessed few scalable issues where the search would take a while when the index size is too large.

OpenSearch Service presents a cost-effective pricing model, allowing users to pay solely for their usage without being burdened by minimum fees or upfront commitments. Its seamless integration with various AWS services enhances its adaptability for a wide range of data analysis requirements and also I love using it isn't it enough.

• We found Apache Lucene to be extremely performant in querying large amounts of data and retrieving the correct files based on the metadata provided.
• The online community offers great support for the product. Even though it is an open source tool, it is not difficult to find help online for it.
• When we were creating a proof of concept application, we found that the software worked just as well, while being run locally on a resource-limited PC.

Incentivized

• Gives us millisecond response times
• Mainly open-source
• Integration Seamlessly with AWS
• Has a very big community so problems are fixes sooner then later

• User interface for setup and maintenance would be helpful.
• Easier cloud/cluster setup.
• Better, centralized documentation.

Incentivized

• Needs more descriptive documentation
• The UI feels a bit old
• Some functionality still doesn't work correctly

The search and index performance of [Apache] Lucene is excellent and the quality of results is good, if not better. For implementing it with small scale applications it is a no brainer, Lucene is the best and most cost effective solution. Learning curve is not too steep either.

Well as I said, Elastic is behind paywall now and managing OpenSearch through AWS is so seamless that we just love it. It gets updates faster we don't have to manage separate infra and many other settings to work with elastic search and some of the tools that it provides are better then them.

• Being an open source project we did not have to pay any licensing fees for using Apache Lucene. It has greatly improved our search functionality in our web apps.

Incentivized

• Well we had 200 ms response times which decreased to 100ms while using OpenSearch
• Easy to use security plugins we dont need external IAM
• Super Easy Integration with many AWS Services such as kinsesi data stream and dynamoDB
