Lucene?

[Beatrix Willius]

Hi Lynn,

my application archives email. Lots and lots of email. Searching is done for the usual suspects. From, To, Date, Subject are no problem and are pretty fast. A major bottleneck is searching in the message body. Valentina is just too slow for a simple *searchtext* search. Users expect to enter their search terms without any wildcards and they expect their search results in less than a second.

I can make some benchmarks tomorrow.

Also important is that Lucene offers more search options than anyone at Paradigma could easily implement:

Powerful, Accurate and Efficient Search Algorithms
	• ranked searching -- best results returned first
	• many powerful query types: phrase queries, wildcard queries, proximity queries, range queries and more
	• fielded searching (e.g. title, author, contents)
	• sorting by any field
	• multiple-index searching with merged results
	• allows simultaneous update and searching
	• flexible faceting, highlighting, joins and result grouping
	• fast, memory-efficient and typo-tolerant suggesters
	• pluggable ranking models, including the Vector Space Model and Okapi BM25
	• configurable storage engine (codecs)
