The first salvo of what we've been hinting about re. server side
faceted browsing over Unlimited Data within configurable
Interactive Time-frames is now available for experimentation at:
Enter search pattern: Microsoft
You will get the usual result from a full text pattern search
i.e., hits and text excerpts with matching patterns in boldface.
This first step is akin to throwing your net out to sea while
Now you have your catch, what next? Basically, this is where
traditional text search value ends since regex or xpath/xquery offer little when the structure of
literal text is the key to filtering or categorization based
analysis of real-world entities. Naturally, this is where the value
of structured querying of linked data starts, as you seek to use
entity descriptions (combination of attribute
and relationship properties) to "Find relevant things".
Continuing with the demo.
Click on "Properties" link within the Navigation section of the
browser page which results in a distillation and aggregation of the
properties of the entities associated with the search results. Then
use the "Next" link to page through the properties until to find
the properties that best match what you seek. Note, this particular
step is akin to using the properties of the catch (using fishing
analogy) for query filtering, with each subsequent property link
click narrowing your selection further.
Using property based filtering is just one perspective on the
data corpus associated with the text search pattern; thus, you can
alter perspectives by clicking on the "Class" link so that you can
filter you search results by entity type. Of course, in a number of
scenarios you would use a combination of entity types and entity
properties filters to locate the entities of interest to you.

This time the service made zero such statements, sorry.
