Hi Lucene users,
Enlightened by the discussion "Can I run Lucene in google app engine?
[http://www.nabble.com/Can-I-run-Lucene-in-google-app-engine--td23017742.html],
I implemented a google datastore based Lucene component, GAELucene, which can
help you to run search applications on google app engine.
The main clazz of GAELucene include:
* GAEDirectory - a read only Directory based on google datastore.
* GAEFile - stands for an index file, the file's byte content will be
splited into multi GAEFileContent.
* GAEFileContent - stands for a segment of index file.
* GAECategory - the identifier of different indices.
* GAEIndexInput - a memory-resident IndexInput? implementation like the
RAMInputStream.
* GAEIndexReader - wrapper for IndexReader? that cached in
GAEIndexReaderPool
* GAEIndexReaderPool - pool for GAEIndexReader
The following code snippet demonstrates the use of GAELucene do searching:
Query queryObject = parserQuery(request);
GAEIndexReaderPool readerPool =GAEIndexReaderPool.getInstance();
GAEIndexReader indexReader = readerPool.borrowReader(INDEX_CATEGORY_DEMO);
IndexSearcher searcher =newIndexSearcher(indexReader);
Hits hits = searcher.search(queryObject);
readerPool.returnReader(indexReader);
