Intelligent search has transformed our ecommerce personalization and drives higher conversions
Coveo fits into our workflow as the core engine of our search, which makes our users' experience amazing by providing us with insights on what products are being sold more and what kind of customers in what regions understand or require what kind of products. Those minimalistic details are what Coveo has provided us with and improved our website interaction. The best features Coveo offers include the AI-powered search that analyzes the region, the user, specific products, or preferences and needs, automatically sharing that information. Additionally, the search it provides is extremely fast and features an auto-search option that gives users basic details, images, and offers in the search field itself. The AI-powered search actually helps our team by allowing users to search for products based on their preferences, with caching available that makes the search fast for users. This has increased our throughput time and the number of users engaged with our application, leading to more purchases. The biggest feature I would highlight about Coveo is the AI enhancements and advancements they have made. Beyond that, the website search for products is faster, and we use it for some of our internal employee search applications as well, making it an amazing tool to utilize.

Search performance has transformed customer document access and continues to improve satisfaction
Customer satisfaction has significantly improved since switching to Pulse Elasticsearch and OpenSearch from old legacy services, as many insights from customers indicate that latency has changed dramatically and the speed is significantly better now. For others looking into using Pulse Elasticsearch and OpenSearch, it is definitely recommended to give it a try, especially if old legacy systems that are slow are currently being used. Lately, OpenSearch has come up with a new version that greatly enhances speed, so trying it is encouraged and it will be loved. A review rating of 9 reflects the overall satisfaction with Pulse Elasticsearch and OpenSearch.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I would highly recommend Coveo as it is smart, fast, relevant, and especially suitable for big sites and large e-commerce setups."
"What we are seeing is that our sales have significantly increased by twenty to thirty percent just within one year of using Coveo."
"AI-enabled query suggestions help users return more frequently and build trust in the search capabilities our site offers, allowing us to drive content towards users based on popular queries."
"Coveo provides a search engine experience that is superior when compared to the other search engines available in the market as of now."
"Coveo provides AI-driven search results and proper recommendations based on customer interaction and context, which is very beneficial for us because it improves our order conversion rate, allowing customers to find the exact products they want and see similar products, greatly increasing upselling."
"Customer satisfaction has significantly improved since switching to Pulse Elasticsearch and OpenSearch from old legacy services, as many insights from customers indicate that latency has changed dramatically and the speed is significantly better now."
"It is quite easy, and I think it was really great the way they offered the services."
 

Cons

"While Coveo is overall very fast, I find the development integration somewhat challenging."
"In a general sense, we are not seeing a remarkable return on investment because maintaining Coveo for our search functionality is costly, and we have to balance investments in search versus other areas."
"One area of improvement for Coveo is the size limitation concerning response results."
"I chose eight out of ten because we have some limitations, such as when we share heavy data, where a large number of data takes more time for Coveo to process; that is one area where Coveo needs to improve, but apart from that, it is good."
"I would give Coveo a nine out of ten because the response and everything is fine, but the technical team of Coveo helps us, yet I think it is not one hundred percent."
"I think the way they support the ingesting service for Pulse Elasticsearch and OpenSearch is not really great."
