Averill: I have continued to ponder this issue (several hours now). I have found something interesting (albeit is unfortunate):
(forgive for any following info that is obvious and/or redundant)
There are two basic ways to apply bold attribute:
(1) type Cntrl-b (or use "B" toolbar button in "Font" portion of ribbon) ... or ...
(2) use Font Dialog Box to set Bold attribute. [Naturally, method (1) is most convenient and quickest method.]
Likewise, for Finding/Searching for bold attribute, there are also two ways, both ways using "Find and Replace" dialog box:
(A) type Cntrl-b and under "Find what:" it will say "Format: Font: Bold" .... or ....
(B) use "Format" button at bottom left of dialog box to bring up "Font" dialog box and select "Bold" for the search. After "OK", F/R dialog box will
also say "Format: Font: Bold".
Sooooo, you'd think there would be no difference between methods (1) & (2) for applying Bold attribute, and likewise no difference between methods (A) and (B) for finding bold attribute -- there certainly was no difference before the June update (I am assuming).
But NOW, going forward, it appears that Method (B) for Searching will in fact find
ALL Bolding, no matter which way is used to apply bolding [methods (1) or (2)]. But Method (A) for searching for Bold will ONLY find the Bolding that was applied using method (1) [cntrl-b or "B"
toolbar button].
This is definitely, in my opinion, a bug in the MS-Word program; however, the Bold attribute can still be searched for, just not as conveniently as before by using Cntrl-b.
For past/old/archived documents (pre-June 2019?), it appears that no matter how bold attribute was applied to text, the only way to Find/Search for them is by using method (B) Font dialog box from within the F/S dialog box.
I haven't fully tested this out yet for Italics, but I assume that everything above applies also for Italic attribute.
(I reviewed all of the past "replies" to your initial query, and I didn't see anything that described a similar answer as above. If this doesn't work for you, I would be interested to know.)
