what does "-" mean in everything command

[slarkmonk]

Hello,

I'm not sure the function of "-" symbol.

for example, when I type "doc:everything" to search in my computer, there are 8 results,


but just add a minus symbol in the command and use "doc:everything -" command search again, there are just 6 results left.

And there are some command I use to experiment,
"d: datemodified:today" "d: datemodified:today -"
"parent:d: childcount:<100" "parent:d: childcount:<100 -"

the version include "-" is always less result than it versus, and the order is doesn't matter.

PS:
1:I'm a noob in forum and don't know how to insert local pictures in the article, click the image icon,there are "",what content should write in the middle of label?
2:And I tried to use attachments add files, it seemed fail too.

- will match a literal - in the filename.



Everything operators:
space = AND
| = OR
! = NOT
< > = Grouping
" " = escape operators.

Since minus symbol is not a valid operator, why add "-" in the end of search command will derease results?

why add "-" in the end of search command will decrease results?

"d: datemodified:today"

Find files that were modified today AND are on d: drive.

"d: datemodified:today" "d: datemodified:today -"

Find files that were modified today AND are on d: drive AND contain the string '-'.

So if you have a files named,
"updated-today.txt" & "updated today.txt"
the first search would give 2 results
the second search would only give 1 result (as "updated today.txt" does not contain a '-').
