I was originally became motivated to discuss the Soundex feature after having Claude add a Fuzzy Search option to Relationship Filter gramplet, an expansion of @dsblank’s rework of the Flat Filter gramplet by @bugbear.
A bit of searching only surfaced a few features with Soundex options:
- Find Possible Duplicate People (“Use soundex codes” option)
- Soundex match of People with the
<name>filter rule - Soundex gramplet
And the built-in Soundex gramplet was unusable on large trees. (It tries to add pop-up menu ALL known surnames. A menu with thousands of surnames causes the GUI to freeze.) And didn’t seem useful when it did work.
Reworked it to be a “Fuzzy Matching” gramplet that does not add as much burden but still gives more features. And has groundwork that hopefully will support adding other Phonetic encoding systems.
