(I have to remember to take of this stupid EXTERNAL thing my emailer puts on
all outside emails...)
Actually, this is the way I understand it right now...
Construct: MATCH 'bug report API_Version:374 OR API_Version:UAR'
Verbose: Perform an FTS search on the order-independent AND'd words 'bug report
API Version 376' OR 'API Version UAR', and return only
records that contain either grouping.
Let's confirm adding on to our last example...
sqlite> insert into data values('UAR report bug 374 API_Version');
sqlite> select * from data where content match 'bug report API_Version:374 OR
API_Version:UAR';
we got bug report API_Version:374 is right here
we got API_Version:UAR right here
UAR report bug 374 API_Version
There's no order dependence at all...
Quotes around the 2nd phrase makes no difference.
sqlite> select * from data where content match 'bug report API_Version:374 OR
"API_Version:UAR"';
we got bug report API_Version:374 is right here
we got API_Version:UAR right here
UAR report bug 374 API_Version
Quotes around the 1st phrase does make a difference:
sqlite> select * from data where content match '"bug report API_Version:374"
OR "API_Version:UAR"';
we got bug report API_Version:374 is right here
we got API_Version:UAR right here
So I'm completely confused as to what quotes do here...

Good day, Michael. Thank you for taking the time to respond.
Per my (possibly ignorant) understanding of the FTS docs, this construct can
be described as such:
Construct: MATCH 'bug report API_Version:374 OR API_Version:UAR'
Verbose: Perform an FTS search on the phrase 'bug report', and return only
records that contain '374' or 'UAR' in the API_Version column.
