AFAIR, I NEVER used "like", because I never knew how it worked.

But, with that 5-char skew that Steve remembered, perhaps it was an
implementation of (standard?) "Soundex"? If so, it would apply only to
alphabetic (maybe alphanumeric?) strings:
   - always do an exact match on the very first char,
   - then match on the (english?) "sound" of the next 3/4/5/6/.. chars.


If QBE has: Like paradox, this would translate to a Soundex code of P632

Then, DB records with Paradox, Poridex, Piridicks, etc (which also
translate to P632) would be matches.

(I've not run the above example).
