Changelog

2.1.5

  • Fix bug #320 which caused result metadata to be nested under search term instead of field name. Thanks Jonny Gerig Meyer for reporting and fixing.

2.1.4

  • Cache inverse document calculation during build to improve build performance.
  • Introduce new method for combining term metadata at search time.
  • Improve performance of searches with duplicate search terms.
  • Tweaks to build process.

2.1.3

  • Remove private tag from lunr.Builder#build, it should be public, thanks Sean Tan.

2.1.2

  • Fix bug #282 which caused metadata stored in the index to be mutated during search, thanks Andrew Aldridge.

2.1.1

  • Fix bug #280 in builder where an object with prototype was being used as a Map, thanks Pete Bacon Darwin.

2.1.0

  • Improve handling of term boosts across multiple fields #263
  • Enable escaping of special characters when performing a search #271
  • Add ability to programatically include leading and trailing wildcards when performing a query.

2.0.4

  • Fix bug in IDF calculation that meant the weight for common words was not correctly calculated.

2.0.3

  • Fix bug #256 where duplicate query terms could cause a 'duplicate index' error when building the query vector. Thanks Bjorn Svensson, Jason Feng, and et1421 for reporting and confirming the issue.

2.0.2

  • Fix bug #255 where search queries used a different separator than the tokeniser causing some terms to not be searchable. Thanks Wes Cossick for reporting.
  • Reduce precision of term scores stored in document vectors to reduce the size of serialised indexes by ~15%, thanks Qvatra for the idea.

2.0.1

  • Fix regression #254 where documents containing terms that match properties from Object.prototype cause errors during indexing. Thanks VonFry for reporting.

2.0.0

  • Indexes are now immutable, this allows for more space efficient indexes, more advanced searching and better performance.
  • Text processing can now attach metadata to tokens the enter the index, this opens up the possibility of highlighting search terms in results.
  • More advanced searching including search time field boosts, search by field, fuzzy matching and leading and trailing wildcards.

1.0.0

  • Deprecate incorrectly spelled lunr.tokenizer.separator.
  • No other changes, but bumping to 1.0.0 because it's overdue, and the interfaces are pretty stable now. It also paves the way for 2.0.0...

0.7.2

  • Fix bug when loading a serialised tokeniser #226, thanks Alex Turpin for reporting the issue.
  • Learn how to spell separator #223, thanks peterennis for helping me learn to spell.

0.7.1

  • Correctly set the license using the @license doc tag #217, thanks Carlos Araya.

0.7.0

  • Make tokenizer a property of the index, allowing for different indexes to use different tokenizers #205 and #21.
  • Fix bug that prevented very large documents from being indexed #203, thanks Daniel Grießhaber.
  • Performance improvements when adding documents to the index #208, thanks Dougal Matthews.

0.6.0

  • Ensure document ref property type is preserved when returning results #117, thanks Kyle Kirby.
  • Introduce lunr.generateStopWordFilter for generating a stop word filter from a provided list of stop words.
  • Replace array-like string access with ES3 compatible String.prototype.charAt #186, thanks jkellerer.
  • Move empty string filtering from lunr.trimmer to lunr.Pipeline.prototype.run so that empty tokens do not enter the index, regardless of the trimmer being used #178, #177 and #174
  • Allow tokenization of arrays with null and non string elements #172.
  • Parameterize the seperator used by lunr.tokenizer, fixes #102.

0.5.12

  • Implement lunr.stopWordFilter with an object instead of using lunr.SortedSet #170, resulting in a performance boost for the text processing pipeline, thanks to Brian Vaughn.
  • Ensure that lunr.trimmer does not introduce empty tokens into the index, #166, thanks to janeisklar

## 0.5.11

0.5.10

0.5.9

  • Remove recursion from SortedSet#indexOf and SortedSet#locationFor to gain small performance gains in Index#search and Index#add
  • Fix incorrect handling of non existant functions when adding/removing from a Pipeline #146 thanks to weixsong
