The problem with enterprise search systems is that companies often buy a product expecting it to be as good as a public search engine out of the box, but it doesn't work that way.

Companies can have a great intranet search experience, but it requires time to properly configure the schema, train taxonomies, tune relevance, and understand the resources required to make it work quickly and reliably.

Document processing pipelines often require customization to meet the above requirements, and multi-lingual search may never be perfect within an organization due to differences in the way wordbreaking is done.

Some companies do put a lot of effort into doing this right and getting the best experience possible today, but most don't.
