PossitionIndex (was: Re: [Zope-dev] ZCatalog phrase indexingr evisited)

[sean.upton@uniontrib.com]

A lot of folks who do "power searches," say, librarians or other trained
researchers, familiar with the bells and whistles of more powerful search
engines, will want a simple operator for proximity, with the ability to
specify proximity depth:

For example:

Lexis-Nexis:	Sean w/2 Upton 	(where w/2 is within 2 words)
			Also, lexis doesn't count stop-words in proximity
indexes.
Folio/Nextpage:	"Sean Upton"@2

IMHO, the syntax is clean and very brief in the Lexis-Nexis case and should
suppliment a more generic 
	Sean ... Upton
style search.

These both look like good spellings, and I think "erik near enge" would
be a good alias for "erik ... enge" as well..
