Manage tags shows wrong count

[sam]

Hello,
I'm on Calibre 5.12 on OsX.

Steps:
- Right click on Tags
- Manage Tags
- On the Category Editor (Tags) I order by count

I wanted to show the books having the tags whose count was just 1.
So I right clicked on the tag names having count 1 and chose "Search the library for 'Name Of The Tag'"

=> In most cases the count was correct but in many other cases it was wrong, meaning that even thought the count was 1 I could see multiple books in the search result.

I've verified this for other counts, for example tags showing count = 2 shows 2 result in most cases but in some cases they show many more book results (in one case 18 instead of 2)

Anything else I can do to help debugging this?

Ah, I think I've figured out one of the problem.
Example:
Let's say a tag is called "Anatomy & Physiology"
On the Category Editor (Tags) by right clicking and "Search the library for Anatomy & Physiology" will also match books containing the tag "Human Anatomy & Physiology"

Changing the component for this bug.

@charles: Should the category editor be generating = searches? It doesnt
do that at the moment.

@OP: You can search for books having a number of tags as follows:

You can search for the number of items in multiple-valued fields such as tags. These searches begin with the character #, then use the same syntax as numeric fields. For example, to find all books with more than 4 tags use tags:#>4. To find all books with exactly 10 tags use tags:#=10.

@kovid: you are right, it should use an exact match search. Done.
