Posted by almosthere (almosthere), 11 September 2002Right... I've just discovered something I've never seen before and was wondering what was known / thought of about it...
For those who don't know -
The 'soundex' function in a where clause matches using the phonetics of the word passed to it. For example :
... would match 'matthew', 'mathew' and a few other words (probably 'mathu' too).
I mentioned this to an Oracle programmer I know and she told me the function was erratic and known to cause problems.
Anyone have any ideas about this? It seems tremendously useful to me - especially with regard to searches. Are there any known problems with the way it breaks the words down into phonetics? Does it actually break them down or is it "cheating"?
Posted by admin (Graham Ellis), 11 September 2002I do know that "soundex" libraries and similar have been around for many many years, but they don't seem to have taken over the world; I've always worried about exactly what they will and won't match and how predicatbale they are, and either others share my worries, or they have proven (as you suggest) to be erratic.
Now MySQL does have an RLIKE that allows you to match those nice regular expresson things
