-----------------------------------
Summary: BasicQueryLanguageProvider#queryResources does not return
all selected fields
Key: SLING-7303
URL: https://issues.apache.org/jira/browse/SLING-7303
Project: Sling
Issue Type: Bug
Components: JCR
Affects Versions: JCR Resource 2.9.2
Reporter: Dirk Rudolph
The method named above iterates over the values returned from the row using
{{jcrRow.getValues()}} - this unfortunately doesn't take all capabilities of
oak into account. To name just a few:
1) Selectors: Querying with selector like {{select p.\[jcr:score] from
\[cq:Page] as p where contains(p.\[*], 'some text')}} returns 0.01 as score
because the actual score is stored in {{p.jcr:score}} and the fallback is [an
open
todo|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-jcr/src/main/java/org/apache/jackrabbit/oak/jcr/query/RowImpl.java#L82].
2) Advanced query functionalities: Queries containing for example rep:facet()
are not taken into account at all, as the colNames are not iterated, only the
values which only expose stored fields. See the following for all the cases:
[LucenePropertyIndex.java#L1628|https://github.com/apache/jackrabbit-oak/blob/jackrabbit-oak-1.6.1/oak-lucene/src/main/java/org/apache/jackrabbit/oak/plugins/index/lucene/LucenePropertyIndex.java#L1628]
Along with this bug the unit tests for a couple of scenarios should be added to
cover what BasicQueryLanguageProvider is doing.
