Michael McCandless commented on LUCENE-1673: -------------------------------------------- I think deprecating DateTools makes sense, though, we should add simple code fragments showing the migration. NumericRangeQuery's javadocs are great, but I'd like to crispen it up, by decoupling "how you use it" from "how it's implemented". EG lead right off with a "for the impatient, this is how it's used", and then a separate section detailing how it works, what precisionStep means (and tradeoffs of high/low values for it), the reference to the full paper, etc. But we can iterate on the javadocs in the separate issue, too. > Move TrieRange to core > ---------------------- > > Key: LUCENE-1673 > URL: https://issues.apache.org/jira/browse/LUCENE-1673 > Project: Lucene - Java > Issue Type: New Feature > Components: Search > Affects Versions: 2.9 > Reporter: Uwe Schindler > Assignee: Uwe Schindler > Fix For: 2.9 > > Attachments: LUCENE-1673.patch, LUCENE-1673.patch, LUCENE-1673.patch > > > TrieRange was iterated many times and seems stable now (LUCENE-1470, > LUCENE-1582, LUCENE-1602). There is lots of user interest, Solr added it to > its default FieldTypes (SOLR-940) and if possible I want to move it to core > before release of 2.9. > Before this can be done, there are some things to think about: > # There are now classes called LongTrieRangeQuery, IntTrieRangeQuery, how > should they be called in core? I would suggest to leave it as it is. On the > other hand, if this keeps our only numeric query implementation, we could > call it LongRangeQuery, IntRangeQuery or NumericRangeQuery (see below, here > are problems). Same for the TokenStreams and Filters. > # Maybe the pairs of classes for indexing and searching should be moved into > one class: NumericTokenStream, NumericRangeQuery, NumericRangeFilter. The > problem here: ctors must be able to pass int, long, double, float as range > parameters. For the end user, mixing these 4 types in one class is hard to > handle. If somebody forgets to add a L to a long, it suddenly instantiates a > int version of range query, hitting no results and so on. Same with other > types. Maybe accept java.lang.Number as parameter (because nullable for > half-open bounds) and one enum for the type. > # TrieUtils move into o.a.l.util? or document or? > # Move TokenStreams into o.a.l.analysis, ShiftAttribute into > o.a.l.analysis.tokenattributes? Somewhere else? > # If we rename the classes, should Solr stay with Trie (because there are > different impls)? > # Maybe add a subclass of AbstractField, that automatically creates these > TokenStreams and omits norms/tf per default for easier addition to Document > instances? -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
