4月18日 武汉 源创会开始报名，送华为开发板
Apache Lucene 4.10.3 发布，它是一个高性能的全 java 编写的文本搜索引擎库。几乎适用于所有需要全文搜索的应用程序。此版本中主要修复了 12 个 Bug。
Bug 修复：
-
LUCENE-6019 , LUCENE-6117 : Remove -Dtests.assert to make IndexWriter infoStream sane.
(Robert Muir, Mike McCandless)
-
LUCENE-6161 : Resolving deletes was failing to reuse DocsEnum likely causing substantial performance cost for use cases that frequently delete old documents
(Mike McCandless)
-
LUCENE-6192 : Fix int overflow corruption case in skip data for high frequency terms in extremely large indices
(Robert Muir, Mike McCandless)
-
LUCENE-6207 : Fixed consumption of several terms enums on the same sorted (set) doc values instance at the same time.
(Tom Shally, Robert Muir, Adrien Grand)
-
LUCENE-6093 : Don't throw NullPointerException from BlendedInfixSuggester for lookups that do not end in a prefix token.
(jane chang via Mike McCandless)
-
LUCENE-6279 : Don't let an abusive leftover _N_upgraded.si in the index directory cause index corruption on upgrade
(Robert Muir, Mike McCandless)
-
LUCENE-6287 : Fix concurrency bug in IndexWriter that could cause index corruption (missing _N.si files) the first time 4.x kisses a 3.x index if merges are also running.
(Simon Willnauer, Mike McCandless)
-
LUCENE-6205 : Fixed intermittent concurrency issue that could cause FileNotFoundException when writing doc values updates at the same time that a merge kicks off.
(Mike McCandless)
-
LUCENE-6214 : Fixed IndexWriter deadlock when one thread is committing while another opens a near-real-time reader and an unrecoverable (tragic) exception is hit.
(Simon Willnauer, Mike McCandless)
-
LUCENE-6105 : Don't cache FST root arcs if the number of root arcs is small, or if the cache would be > 20% of the size of the FST.
(Robert Muir, Mike McCandless)
-
LUCENE-6001 : DrillSideways hits NullPointerException for certain BooleanQuery searches.
(Dragan Jotannovic, jane chang via Mike McCandless)
-
LUCENE-6306 : Merging of doc values and norms now checks whether the merge was aborted so IndexWriter.rollback can more promptly abort a running merge.
(Robert Muir, Mike McCandless)
