Or grouping of a number of key words within a document?
'JAMES LESTER CAINE BIRTH' Provide a result set and allow processing on
the result set.

Currently the requirements are quite simple, but if the 1Gb of documents
that I currently have access to in house are indexed properly, then ANY
sort of full-text search should be possible without rescanning all that
data. Yes I can carry on using external libraries to achieve the same
result, but I'd be happier if the engine was controlling more of it. I
still think that this is a combination of internal and external
functions, but the 'systems tables' need to be usable by anybody as
extensions are developed.
