What do you like best?
Coveo has the flexibility to provide cross-channel content search functionality. In addition the faceted search ability is customer friendly, as long as "we" tag the content properly.
I find it it somewhat amazing that we are able to search & provide results from any one of our portals, even those that need passwords.
What do you dislike?
Really like the tool, have used it in two different companies. However, it take a bit of time and testing to get the search functions correctly configured. Just know that planning, testing and time is required to get it right. Once right, it is great!
Recommendations to others considering the product
I recommend Coveo.
Just be certain to have a consolidated objective, understand what you will be providing the end-user, and plan for the build.
What business problems are you solving with the product? What benefits have you realized?
We solved the cross website search ability, including our CRM [SFDC]. We were surprised at the accuracy of searching other websites and portals we own. We wanted all of our disparate assets to be combined in a faceted & tabular manner for ease of finding information.
Coveo has done this extremely well.
In addition we wanted each language site to have a localized search first, then apply the English assets. This is no issue.
