There is no way to get a clear, intuitive classification like this
from an unsupervised clustering algorithm. You rely on prior knowledge
(that these are companies, that they produce laptops, etc.).

I would use faceting and pre-tag your documents with all the labels
you may wish to display in your user interface. This will be more
reliable and faster. You can then add clustering on top of that as a
form of "dynamic faceting" which users may use to lookup keywords/ key
phrases of groups of search results not covered in regular facets.

The plugin contains the required documentation. Like I said though,
the results will be disappointing if you expect perfect ontology from
raw text.
