Cancelling out part of a saved search.

ownedbycats · 09-11-2021, 01:43 AM

I have this search, called Currently Reading:

Code:

#read:yes
AND #percentread:100
AND NOT #fanficstatus:"=In-Progress"
AND (#lastread:=thismonth OR #lastread:>14daysago)

Now I want to make a different search, with one key difference in line #3:

Code:

#read:yes
AND #percentread:100
AND #fanficstatus:"=In-Progress"
AND (#lastread:=thismonth OR #lastread:>14daysago)

Just out of curiosity to see if I could shorten this, I searched search:"=Recently Finished Reading" AND #fanficstatus:"=In-Progress". obviously it just cancelled each other out to get zero results.

Is there a way to do this, or do I need to duplicate the entire thing?

Yes, the Boolean expression "A and not A" is by definition always false.

Creating a second saved search is the easiest.

Another way would be to make a saved search:

Code:

#read:yes
AND #percentread:100
AND (#lastread:=thismonth OR #lastread:>14daysago)

For this example I name this search "reading_base".

Now make two saved searches:

Code:

search:"=reading_base" AND #fanficstatus:"=In-Progress"

and

Code:

search:"=reading_base" AND NOT #fanficstatus:"=In-Progress"
