NOTE: these release notes are not up to our normal stands due to waiting far too long between releases. We will attempt to release more frequently and more carefully annotate release notes.

• New method to create in-memory indexes (#452)

Enhancements

• New experimental indexing scheme smolder
• All bleve utilities migrated to single bleve cmd (#430)
• Index upside_down performance optimizations
• Searcher performance optimizaitons

Bug Fixes

• Shingle filter now stateless, was producing bogus output (#431)
• Fix panic in collector when skipping more than total hits (#453)

v0.4.0

Behavior Changes

• POSSIBLE BREAKING CHANGE - Byte Array Converters removed - SEE #392
• Firestorm indexing scheme removed
• Build tags added around references to persistent storage, making it slightly more possible to use in Google App Engine

Enhancements

• Match query supports changing default operator AND/OR
• Facet speedups
• UpsideDown indexing scheme query perf improvements
• Index API changes to make internal document identifiers opaque
• Ability to sort results by indexed fields
• Support read_only flag for boltdb indexes
• Improved unit test code coverage to 74%
• Removed nex query string lexer, replaced with custom lexer
• New query string lexer supports escaping reserved characters
• Minor text analysis perf tweaks

Bug Fixes

• Corrected Advance() method of regexp, prefix and fuzzy searchers #342
• Indexing of primitives fixed inside map/struct #389
• Moss handing of 0-length values
• Docs updated for date range querying #382

v0.3.0

Behavior Changes

• Search result hits with the same score will now be returned sorted by document ID ascending, previously they were sorted by document ID descending. This behavior is not guaranteed, so applications should not rely on it.
• CJK analyzer now uses unicode tokenizer and cjk width filter, this enhances compatibility with Lucene/ES, though it changes behavior in some cases.
• Whitespace tokenizer now faster and behaves more like the one with the same name in Lucene/ES

Enhancements

• Multi-term searches now check the setting of DisjunctionMaxClauseCount earlier in the process, avoiding unnecessary CPU usage
• Simplified date parsing in queries, now always use top-level setting QueryDateTimeParser
• Query Strings now support date range queries
• SearchRequest now has a Validate() method which can report invalid facet requests
• Performance - loading stored fields and highlighting result snippets now only does a single lookup
• Performance - top score collector faster by doing less work for hits with scores that cannot be in the top N
• New token filter to handle camel cased input
• Standardized behavior of index mapping with anonymous struct fields

Bug Fixes

• Fix metrics stats serialization crash on Windows
• Fix JSON marshaling of MatchNone
• Properly initialize stats object for in-memory indexes
• Unregister index from expvar on Close()
• Configuring ngram filter more straightforward and robust

v0.2.0

Enhancements

• QueryString query now supports wildcard and regexp queries

Bug Fixes

• Concurrent map write in bleve.Batch reuse has been fixed
  • REMINDER: bleve.Batch must only be used by a single goroutine
• The vendor/manifest file included newer SHA for go-metrics and protobuf than had actually been tested. We can't say those versions don't work, but we have rolled them back to versions that we know do. We now test the vesions in the manifest as a part of our CI test suite.

Initial Release

Only 1 year, 11 months, and 22 days after our initial github commit, we've gotten our act together and produced our first numbered release. Subsequent releases will contain a more typical itemized list of changes.
