Hi,
Thank you for all the details, I was able to log-in and check your configuration. I think the confusion is caused by that one extra result you get when you search “wives” – that is taxonomy term result, and the synonyms does not apply to them, as the index table is not used there.
As i understand it, typing in “wife” will now bring the same results as typing in “wives”.
Not exactly – because it is not the search keyword replaced, but additional keywords indexed as synonyms, that is different a bit. The keyword occurence of non-synonyms can be different. The overall results set should be almost identical, but the order can be different.
I tried the wife, wives, wifes combinations, but the results were identical, aside from “wives” – which also matches an additional taxonomy term as result, where the index table does not apply:

If you don’t want to show that extra woocommerce category as result, you can disable it here: https://i.imgur.com/jLwOHEN.png
