I have used firebolts for my work as well as personal projects such as building our internal knowledge base where we would need to search through millions of documents.
They've been very helpful in providing us an easy way of searching through large amounts of information while also ensuring that they are able to provide results within milliseconds. Nothing really comes to mind but if it is something specific about this product look into their documentation because there seems to be quite a few problems people are having with finding answers to questions which can often lead to frustration when trying to find solutions. The benefits include being able to quickly access large databases using tools like Excel and Sharepoint without needing to use SQL queries (which sometimes don't return accurate results).
