Search insights have reduced no-result queries and guide visitors quickly to relevant content
In my opinion, the best features Coveo offers are that it's quick, it's easy to navigate, and if you have something you want to know, Coveo is very helpful in helping you find out how to get the information that you need and sort the information that you need. Of those features, the main thing I find myself appreciating the most in my day-to-day work is being able to find what I need without spending a huge amount of time. The speed and easy navigation are important; there are other tools that do the same thing, but finding what I need quickly really matters.

Scales linearly and vertically; primarily used in AI
If I am not wrong, IDOL is working to release improvements in new capabilities in the next six months. There is room for improvement in some very important capabilities in visual analytics. They have been focusing on improving the face recognition algorithm. The accuracy of object detection could be improved as well and I know they are working on that at the moment. I would like to see some machine learning capabilities added to the next release.

Quotes from Members

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

Pros

"Coveo positively impacted our organization by drastically reducing the time needed to provide solutions on the support case side, as agents no longer have to sift through all documents, resulting in decreased response time and reduced case volume since customers can verify the knowledge available before creating a case."
"Coveo already has a very good e-learning platform with multiple courses to learn and certifications to achieve, so it is very good in terms of the learning curve for new users or developers working with it."
"In terms of accuracy and reliability of output, I believe Coveo is probably the best in market scenarios."
"I would highly recommend Coveo as it is smart, fast, relevant, and especially suitable for big sites and large e-commerce setups."
"After migrating to Coveo, it took less than 10 milliseconds to load all this data."
"Coveo provides a search engine experience that is superior when compared to the other search engines available in the market as of now."
"Coveo has positively impacted my organization by cutting down the number of no result searches from something like 15% to about 5%, which is huge, saving calls to call center people and probably preventing people from seeking out products from our competitors, so we get people to pages that they want more quickly and more effectively."
"One of the standout features of Coveo is its AI-powered search relevance, which helps users find the right content quickly."
"IDOL is a scalable solution: If a client needs to process more unstructured media content, they can scale IDOL both linearly and vertically, and you can scale this solution very easily."
"Satisfaction and ability to find relevant content has increased over 50% based on our before and after survey results."
"Speed improvements over older Fetch architecture."
"Capability of processing and analysing unstructured data, like audio and video analysis."
"Enterprise search success (finding what documents you're looking for) has gone up over 30% with users finding their hit on the first page of results as opposed to the 2,3,4th or giving up entirely."
"IDOL has several important visual analytics, like face recognition and object detection and recognition."
 

Cons

"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 pricing was definitely on the higher side, and the professional services were also quite costly."
"One area of improvement for Coveo is the size limitation concerning response results."
"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."
"I faced some challenges regarding the accuracy of the search results with Coveo."
"The learning curve can be steep for new developers, especially when working with relevance tuning, query pipelines, and advanced configurations."
"The main reason I rate it an eight out of ten is that while Coveo is very capable, there is still some room for improvement regarding the developer experience."
"IDOL's tech support needs improvement."
"The interface needs to be mobile friendly, which I understand is in the backlog of future improvements."
"On-premise implementation and installation is very complicated."
"Technical support could improve a lot."
"Understanding how to optimize Lua Scripting configuration to improve performance. Lua Scripts added to a CFS configuration can cause the CFS processing to slow down, if the scripts are not scoped to only run against specific indexing jobs or database content."
"There is room for improvement in some very important capabilities in visual analytics. They have been focusing on improving the face recognition algorithm. The accuracy of object detection could be improved as well and I know they are working on that at the moment."
