Searching for empty "maven.classifier" doesn't work

[marcinus]

• What problem are you trying to solve?

Neither of the following requests return any results:

http://nexus-host/service/rest/v1/search/assets?repository=company-snapshots&group=com.company.product&name=some-service&maven.baseVersion=2.0.5-SNAPSHOT&maven.extension=jar&maven.classifier=""

http://nexus-host/service/rest/v1/search/assets?repository=company-snapshots&group=com.company.product&name=some-service&maven.baseVersion=2.0.5-SNAPSHOT&maven.extension=jar&maven.classifier=

http://nexus-host/service/rest/v1/search/assets?repository=company-snapshots&group=com.company.product&name=some-service&maven.baseVersion=2.0.5-SNAPSHOT&maven.extension=jar&maven.classifier

Whereas the following returns results (the only difference is lack of maven.classifier selector)

http://nexus-host/service/rest/v1/search/assets?repository=company-snapshots&group=com.company.product&name=some-service&maven.baseVersion=2.0.5-SNAPSHOTS&maven.extension=jar

• Do you have a workaround you are using at present?

Yes. I can use the working query with jq selector:
jq -r '.items | map(select(has("maven2") and (.maven2 | has("classifier") | not))) | sort_by(.lastModified) | reverse | last | .downloadUrl'

• What feature or behavior is this required for?

Integration with pipelines downloading the latest SNAPSHOT version.

• How could we solve this issue? (Not knowing is okay!)

Probably there's an issue with Elasticsearch index on this property?

• Tell us about your Nexus Repository deployment: what version, operating system, and database are you using?

OSS 3.58.1-02, RHEL8.10 and Orient Embedded DB

• Anything else?
