Got "CC-BY-NC-SA-3.0 AND CC-BY-SA-3.0" for file mentioning elements under CC-BY-SA-3.0

Description

Not sure if this is a bug, but an issue, at least for me.
When scanning the attached custom-content.html file (attached) , I get "CC-BY-NC-SA-3.0 AND CC-BY-SA-3.0" for detected_license_expression_spdx, while the content only refers to elements under CC-BY-SA-3.0. (see attached json file)

How To Reproduce

git checkout v32.0.8
./configure
source venv/bin/activate
scancode -h
scancode --license --copyright --json-pp scancode_result.json custom-content.html 

System configuration

For bug reports, it really helps us to know:

• What OS are you running on? Ubuntu 22.04.3 LTS
• What version of scancode-toolkit was used to generate the scan file? v32.0.8
• What installation method was used to install/run scancode? source download

custom-content.html.txt

scancode_result.json

Thanks for the report. I will make a dedicated fix commit to show what the simple fix is FWIW.

@dotarjun here is a change that may fix things:
In src/licensedcode/data/rules/cc-by-nc-sa-3.0_22.RULE add double curly braces to make a part a "key phrase":

---
license_expression: cc-by-nc-sa-3.0
is_license_notice: yes
relevance: 100
ignorable_urls:
    - http://creativecommons.org/licenses/by-nc-sa/3.0/deed.en_US
