-------------------------------------
Hi Dave,
> I've probably failed to follow your contribution guidelines
The problem might be that we don't follow the documented guidelines...
I'm sorry about that. I will assign the issue to me.
It would be good to have a test case. Not sure where to put it best.
> OakAnalyzer applies LowerCaseFilter and WordDelimiterFilter in wrong order

> Key: OAK-9145
> URL: https://issues.apache.org/jira/browse/OAK-9145
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: indexing, jcr, lucene
> Environment: Discovered while performing DAM searches in Adobe
> Experience Manager.
> Searching for _savings_, the damAssetLucene index (which uses the default
> OakAnalyzer) does not find an asset named _savingsAccount.svg_.
> Upon configuring the index's analyzers
> (_/oak:index/damAssetLucene/analyzers_) to apply WordDelimiterFilter before
> LowerCaseFilter, the correct behaviour was seen.

> I believe OakAnalyzer applies LowerCaseFilter and WordDelimiterFilter in the
> wrong order. WordDelimiterFilter is invoked with the GENERATE_WORD_PARTS
> flag, which splits camelCase/PascalCase into multiple terms, but since the
> LowerCaseFilter is applied first, the mixed-case is lost and the terms can't
> be split.
