Is your feature request related to a problem? Please describe.

Usually, a note contains several tags. Now left clicking on a tag will automatically filter out notes containing that tag. But you can only choosing one tag everytime.
How can I choose multi tags at same time so that could filter my expecting notes in output?

Describe the solution you'd like

method 1 : Add multi checkbox.

method 2 : When mouse left clicking on different tags consecutively, it means selecting multiple tags at the same time. The program filters notes that containing multiple tags that match "and" conditions;
Left click on the same tag to toggle the selected or canceled status.

method 3 : users can enter multiple tag keywords in the input box, with each keyword separated by a space.

For now, tag that assigned to currunt note will be bolded auto, but it is not prominent enough.
Though user can assign tags any bg-colors anytime, but I prefer to let it auto heighlighted with color on its font. And for method 1 and 2, when user multi choosing tags, the tags be chosen will be auto heighlighted.

eg. note [mynote] contains 3 tags , user could be able to multi choosing tags and , then note [mynote] will be filtered out as result which user expecting for.

I'm not sure if I understand your feature request. You can already Ctrl+click multiple tags to show the notes of all those tags...

Sorry for my poor English.

As you said "Ctrl+click multiple tags to show the notes of all those tags" - by this way, tags such as 'aa' 'bb' 'cc'... will be processed as meeting the filter query's condicton "OR" - any notes that assigned tag 'aa' or tag 'bb' or tag 'cc', that will be showed.

What I want is tags meet the filter query's condicton "AND", so only if the notes assigned tag 'aa' and tag 'bb' and tag 'cc', both 2 or more tags be assigned to the same note that will be showed.

For example:
note1 is assigned tags 'aa' 'bb' 'cc'
note2 is assigned tags 'aa' 'ff' 'ee'

NOW: when I click multiple tags 'aa' and 'bb', both note1 and note2 will be showed as results since these 2 tags satisfy the query filtering of "OR";

REQUEST: when I click multiple tags 'aa' and 'bb', thers is only 1 result be showed - note1，since only note1 was assigned both tag 'aa' AND 'bb'.

And "Ctrl+click" seems not so convenient to simultaneously press Ctrl and mouse clicking，so I suggest method 1 or method 2 or method 3 that mentioned above. You can keep "Ctrl+click" as original's function.

By this improvement, users can efficiently and quickly find their target notes from a large number of tags and do not need to select target notes from numerous filtering results.

I don't think any AND search will come. The note search is very complex already in the background and also there is no good way of doing it in the interface.

Method 1 would no one understand and clicking a tag already does filter regardless of any checkbox
Method 2 is already implemented.
Method 3 already searches for tags itself and will never do any filtering.

You can always play around with the script engine, since you have access to all notes and tags there!
