Lucene是一套用于全文檢索和搜尋的開源程式庫，由Apache軟件基金會支持和提供。Lucene提供了一個簡單確強(qiáng)大的應(yīng)用程式接口，能夠做全文索引和搜尋，在Java開發(fā)環(huán)境里L(fēng)ucene是一個成熟的免費(fèi)開放源代碼工具;就其本身而論，Lucene是現(xiàn)在并且是這幾年，最受歡迎的免費(fèi)java資訊檢索程式庫。人們經(jīng)常提到資訊檢索程式庫，就像是搜尋引擎，但是不應(yīng)該將資訊檢索程式庫與網(wǎng)搜索引擎相混淆。
成都做網(wǎng)站、網(wǎng)站設(shè)計(jì),成都做網(wǎng)站公司-成都創(chuàng)新互聯(lián)已向上1000+企業(yè)提供了,網(wǎng)站設(shè)計(jì),網(wǎng)站制作,網(wǎng)絡(luò)營銷等服務(wù)!設(shè)計(jì)與技術(shù)結(jié)合,多年網(wǎng)站推廣經(jīng)驗(yàn),合理的價格為您打造企業(yè)品質(zhì)網(wǎng)站。
Lucene 3.6 包含大量的 bug 修復(fù)、優(yōu)化和改進(jìn)，主要內(nèi)容有：
* 完全支持 Java 7，要求 JDK 7u1
* TypeTokenFilter filters tokens based on their TypeAttribute.
* Fixed offset bugs in a number of CharFilters, Tokenizers and TokenFilters that could lead to exceptions during highlighting.
* Added phonetic encoders: Metaphone, Soundex, Caverphone, Beider-Morse, etc.
* CJKBigramFilter and CJKWidthFilter replace CJKTokenizer.
* Kuromoji morphological analyzer tokenizes Japanese text, producing both compound words and their segmentation.
* Static index pruning (Carmel pruning) removes postings with low within-document term frequency.
* QueryParser now interprets '*' as an open end for range queries.
* FieldValueFilter excludes documents missing the specified field.
* CheckIndex and IndexUpgrader allow you to specify the specific FSDirectory implementation to use with the new -dir-impl command-line option.
* FSTs can now do reverse lookup (by output) in certain cases and can be packed to reduce their size. There is now a method to retrieve top N shortest paths from a start node in an FST.
* New WFSTCompletionLookup suggester supports finer-grained ranking for suggestions.
* FST based suggesters now use an offline (disk-based) sort, instead of in-memory sort, when pre-sorting the suggestions.
* ToChildBlockJoinQuery joins in the opposite direction (parent down to child documents).
* New query-time joining is more flexible (but less performant) than index-time joins.
* Added HTMLStripCharFilter to strip HTML markup.
* Security fix: Better prevention of virtual machine SIGSEGVs when using MMapDirectory: Code using cloned IndexInputs of already closed indexes could possibly crash VM, allowing DoS attacks to your application.
* Many bug fixes...
