Hi I'm using SOUNDEX mysql function to find similar sounding names from
a table with 2 million distinct names.
Unfortunately there is a single soundex code for every 200,000 names!
Meaning there are only 200,000 distinct codes for 2 million entries.
Is there any other function / library / technique to work around this
immense 1:10 redundancy ?
for example, soundex for 'avis', 'apex' and 'apps' is A120, but I'd
like to differentiate between them in my search - meaning implement a
"stricter" sound comparison than the soundex function offers.
Anything in PHP?
Any pointers would be great

Soundex is rather clumsy for this purpose. Use metaphone() instead, then use
the levenshtein() function to sort the results based on their similarity to
the search term

hey all,
i am currently using a search engine on my site that compares values stored
in the meta tags with what the user types in. any matches return the "title"
of the page, a thumbnail and a link. all is working great.
however, i find myself adding all sorts of variations, i.e. gift, gifts.
i am starting to store both the soundex and metaphone values along with
the keyword for future possibilities.
are there any good primers for...

Hi,
I'm curious about soundex. All I know that it's a way for making spelling-
error-tolerant word matching. What I want to know is whether the soundex
algorithm are made exclusively for english language, or can it be used for
any arbitrary language with satisfactory performance (by 'satisfactory
performance' I meant that it can detect at least 80% spelling-errors). What
about PHP soundex support?
TIA

Hi All,
I have database with names on which I want to use the soundex option.
So I have created two seperate fields for the Lastname and Firstname in
which
I save the Soundex version of a new name I save in the database.
I have the soundex code with the 6 numeric option. So I save for
example in the field
LastnameSE = 600192 and in the FirstnameSE = 545910.

Just wondering if anyone out in query-land has used "Soundex" or "Difference" before to find field values that "sound the same". Similar to LIKE but very different. I was shocked when I heard about it, so I've been playing around. Access doesn't seem to like it. Am I just incompetant?
Thanks

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
