Michael McCandless updated LUCENE-9444: --------------------------------------- Attachment: LUCENE-9444.patch Status: Patch Available (was: Patch Available) Hi [~goankur] – patch looks good! I downloaded and tweaked a bit: * Smoothed wording of some of the javadocs * Fixed indent to two spaces (matching Lucene's style) * Removed catch {{IOException}} / rethrow {{RuntimeException}} – since these methods already throw {{IOException}} we can just throw directly? * Added a few assertions and factored out local variables Net/net I think it is ready! Can you have a look / iterate?

This provides the ordinals that refer to facet labels in the > taxonomy.** > # Lastly TaxonomyReader.getPath(ord) is used to fetch the labels to be > returned. > > Ideally there should be a simple API - *String[] getLabels(docId)* that hides > all the above details and gives us the string labels. This can be part of > *TaxonomyFacets* but that's just one idea. > I am opening this issue to get community feedback and suggestions. > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
