Search engines look for data, not information.  When specifying what we want to find we provide words but we cannot set the informational context.  If we want to find something about hand, we cannot qualify it as to whether we mean a noun (appendage), or a verb (give to).  Do we want to know about a person (Judge Learned Hand), an ovation (applause), an assist, a clock part, or how tall a horse is?  The engines return many thousands of matches without asking which meanings apply.  Nor, if, for example, ovation is the desired meaning, do they reliably search a combination of hand, ovation, applause as those meanings occur, to provide fewer, but more concise results.

Refining meaning requires problematic dialogue and depth of search capability current search engines don't have.  In the greater scheme of IT this is relatively trivial.  The real impact is the careless, self-deceiving habit of calling things information technology that are minimally informational.  This casual approach to meaning ... to information ... is a pervasive problem, leading us to assume we're doing something we are not.   Understanding and imagination are stifled.  Information possibilities and potential are ignored. 

Like the primitive beating of drums to drive off the sun-gobbling eclipse-dragon ...

What we do within IT
... (use computers - beat drums),

What we believe we're doing
... (manage information - frighten dragons),

and What we actually accomplish
... (information incapability - ritual comfort)

... buys into our own mythology.
