Ankur commented on LUCENE-9444: ------------------------------- Thanks [~mikemccand] for making those changes. I made a couple of minor edits * Fixed typo in javadoc * Replaced {code:java} if (parentOrd == INVALID_ORDINAL) { throw new AssertionError("Root ordinal not found for facet dimension: " + facetDimension); }{code} with single line {code:java} assert parentOrd != INVALID_ORDINAL : "Category ordinal not found for facet dimension: " + facetDimension; {code} in method {code:java} public FacetLabel nextFacetLabel(int docId, String facetDimension) throws IOException{code} * Created a pull request as you suggested in one of your earlier comments :) ** [https://github.com/apache/lucene-solr/pull/1893/commits/bf8eaf98901cbe83f23067bea90dfb2f3102603a] Can you take a look and see if it's ready to be committed ? > Need an API to easily fetch facet labels for a field in a document > ------------------------------------------------------------------ > > Key: LUCENE-9444 > URL: https://issues.apache.org/jira/browse/LUCENE-9444 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/facet > Affects Versions: 8.6 > Reporter: Ankur > Priority: Major > Labels: facet > Attachments: LUCENE-9444.patch, LUCENE-9444.patch, > LUCENE-9444.v2.patch > > Time Spent: 10m > Remaining Estimate: 0h > > A facet field may be included in the list of fields whose values are to be > returned for each hit. > In order to get the facet labels for each hit we need to > # Create an instance of _DocValuesOrdinalsReader_ and invoke > _getReader(LeafReaderContext context)_ method to obtain an instance of > _OrdinalsSegmentReader()_ > # _OrdinalsSegmentReader.get(int docID, IntsRef ordinals)_ method is then > used to fetch and decode the binary payload in the document's BinaryDocValues > field. 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
