Hello again, I scanned through some discussions and codes around PForDelta, like LUCENE-1410 <https://issues.apache.org/jira/browse/LUCENE-1410>, LUCENE-2903, <https://issues.apache.org/jira/browse/LUCENE-2903> ConversationBetweenMichaelAndLiLi<http://grokbase.com/t/lucene/dev/10ce0jrv06/strange-problem-of-pfordelta-decoder>. It is great to see so much information, and PForDelta seems to be a promising target. But as I look into the codes in branch-bulkpostings, it seems that most of the algorithms had already been implemented. Then, what is required to do for LUCENE-3892<https://issues.apache.org/jira/browse/LUCENE-3892>, is the main target be the performance improvement, intergration with trunk version, or another implementation from the bottom up?
And another question about development. I am quite curious that some classes such as StandardAnalyzer were not found in the trunk or branch-bulkpostings, but replaced with Mock ones. Then how can I test my old codes, if I want to intergrate these classes with trunk library? Thank you! -- Han Jiang EECS, Peking University, China Every Effort Creates Smile Senior Student
