Laird Nelson commented on MINDEXER-81:
--------------------------------------
I have a concrete use case that I'll elaborate here. I am a new user of Lucene
(no idea what I'm doing :-)) and of the Maven Indexer. Hopefully my
explanation below will give you insight into how a person new to this project
approaches it.
I'd like to write an {{IndexCreator}} that, in the abstract, adds fields to the
index that represent certain contents of {{META-INF/MANIFEST.MF}} files. I'd
like to let users search, for example, for artifacts containing
{{META-INF/MANIFEST.MF}} files with {{Fred}} in their {{Class-Path}} headers.
I see no way to simply write an {{IndexCreator}} (and no other code) to do
this. It seems that I would (with the current architecture) have to edit
{{ArtifactInfo}} to have some new instance variables to store this information.
It also looks like other {{IndexCreator}} implementations that work with
{{META-INF/MANIFEST.MF}} files, like the {{OsgiArtifactIndexCreator}}, do
exactly this: I note that {{ArtifactInfo}}, though it would seem to _want_ to
be a generic sort of class, has fields in it like
[{{bundleSymbolicName}}|https://github.com/apache/maven-indexer/blob/master/indexer-core/src/main/java/org/apache/maven/index/ArtifactInfo.java#L236],
suggesting that for every indexer an edit to {{ArtifactInfo}}'s source code is
necessary. This shouldn't be the case.
