**License Notes**

Currently scancode sees this as two different license notices:

```
"license_detections": [
{
"license_expression": "lgpl-2.0-plus",
"license_expression_spdx": "LGPL-2.0-or-later",
"matches": [
{
"license_expression": "lgpl-2.0-plus",
"license_expression_spdx": "LGPL-2.0-or-later",
"from_file": "refreshjob.cpp",
"start_line": 4,
"end_line": 14,
"matcher": "2-aho",
"score": 100.0,
"matched_length": 92,
"match_coverage": 100.0,
"rule_relevance": 100,
"rule_identifier": "lgpl-2.0-plus_1.RULE",
"rule_url": "https://github.com/nexB/scancode-toolkit/tree/develop/src/licensedcode/data/rules/lgpl-2.0-plus_1.RULE"
},
{
"license_expression": "lgpl-2.0-plus",
"license_expression_spdx": "LGPL-2.0-or-later",
"from_file": "refreshjob.cpp",
"start_line": 14,
"end_line": 16,
"matcher": "2-aho",
"score": 100.0,
"matched_length": 35,
"match_coverage": 100.0,
"rule_relevance": 100,
"rule_identifier": "lgpl-2.0-plus_451.RULE",
"rule_url": "https://github.com/nexB/scancode-toolkit/tree/develop/src/licensedcode/data/rules/lgpl-2.0-plus_451.RULE"
}
],
"identifier": "lgpl_2_0_plus-9612170f-687a-4d34-bd8c-335d7ec0dc45"

```

It might be good to create a separate rule that combines these.
