3 questions

(1) Is it possible to suppress the  from Vortex ?

(2) Is there a way of doing WITHIN (/W) operator simply based on Tokens (rather than the character based one). Lucene (the open source text retrieval engine) implements a token based edit distance metric. Seems this would elimate post processing to some extent (does in Lucene). Regardless, an efficient within token operator would be useful.

(3) I can't get LIKE to support the WITHIN operator at all -- seems like it should, as LIKE3 doesnt do post-processing.

Regards, I'd appreciate an email response as well!

Cheers,
Winton

(1) not ususally, some special licenses allow this.

(2) Yes, you can use W/rex regular expression. The within op is not implemented as and indexed option. This is because not all possible delims can be indexed. Adding some pre-indexed delims has been considered.

(3) You have to enable linear post processing. see: apicp allinear

3) To be clearer, that would be post-processing, not linear searching: <apicp alpostproc on>. And you'll need to allow the within operator too: <apicp alwithin on>.

Sorry... knew I should have looked at the manual on that.
