We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"We have good use cases where stability is everything. So it's a stable solution.""Provides flexibility to tune the relevance and ranking of results."

More Amazon Kendra Pros →

"The most valuable feature is the ability to perform a natural language search.""​Sharding data, Faceting, Hit Highlighting, parent-child Block Join and Grouping, and multi-mode platform are all valuable features.""It has improved our search ranking, relevancy, search performance, and user retention.""One of the best aspects of the solution is the indexing. It's already indexed to all the fields in the category. We don't need to spend so much extra effort to do the indexing. It's great."

Cons
"There are some token limits.""The time it takes for indexing documents could be reduced."

More Amazon Kendra Cons →

"With increased sharding, performance degrades. Merger, when present, is a bottle-neck. Peer-to-peer sync has issues in SolrCloud when index is incrementally updated.""SolrCloud stability, indexing and commit speed, and real-time Indexing need improvement.""Encountered issues with both master-slave and SolrCloud. Indexing and serving traffic from same collection has very poor performance. Some components are slow for searching.""It does take a little bit of effort to use and understand the solution. It would help us a lot if the solution offered up more documentation or tutorials to help with training or troubleshooting.""The performance for this solution, in terms of queries, could be improved."

    Overview

    Amazon Kendra is a highly accurate and easy to use enterprise search service that’s powered by machine learning. Kendra enables developers to add search capabilities to their applications so their end users can discover information stored within the vast amount of content spread across their company. This includes data from manuals, research reports, FAQs, HR documentation, customer service guides, and is found across various systems such as file systems, web sites, Box, DropBox, Salesforce, SharePoint, relational databases, Amazon S3, and more. When you type a question, the service uses machine learning algorithms to understand the context and return the most relevant results, whether that be a precise answer or an entire document. For example, you can ask a question like "How much is the cash reward on the corporate credit card?” and Kendra will map to the relevant documents and return a specific answer like “2%”. Kendra provides sample code so that you can get started quickly and easily integrate highly accurate search into your new or existing applications.
