Technical Specialist at a tech services company with 5,001-10,000 employees

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.

Frequent updates, highly stable, and robust

We have had thousands of users, the solution is highly scalable. We have had a large installation of OpenText Decisiv and there were approximately 6,000 users. The user's roles vary, such as records managers. Additionally, depending on the organization, a lot of our clients are in the federal government which they have different types of roles, but most of them are end-users. They're searching for documents or the records that are in their repository, there are document producers, but most people are searching.
