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.

Robust solution with good value
Microsoft FAST is quite robust. Our clients are quite happy with it. For other users who already have a solution in place, we recommend Microsoft FAST because it is more compatible and you can organize the solution with Microsoft components. If you are with any other third party, there could be a chance that the required output is not what you would expect. But with Microsoft, it will work better. It is compatible with the older generation systems, so you can offer it. On a scale of one to ten, I would give Microsoft FAST an eight because I'm quite comfortable with it.
