I published this comment at The Server Side:============================================Congratulations, and thank you for sharing this very interesting Lucene implementation! Don't forget: it started as a shopping engine for CNET.I didn't try DBSight but I noticed some noizy posts in Lucene-related message boards. I heard about DBSight from a colleague who suggested it "to have full text search

I am going to move from SOLR.Recently someone asked me about 7-9 billions of documents powered by SOLR, memory requirements... 8Gb is not enough for them (OutOfMemoryException). Funny, very funny! Lucene uses FieldCache and even 1000Gb RAM won't handle 10 billion documents with simple nontokenized ISBN field!!!It must be distributed Lucene index. It could be powered by Hadoop. It must be 64

I found this interesting post and repeated tests:- Fastest is NekoHTML.- most correct is NekoHTML.Only URL to nice internet shop (for beauties!) shows the difference, 144 links found with HtmlCleaner, and 116 with NekoHTML. After quick copy-paste to Excel and sorting links I found that some links are simply repeated by HtmlCleaner probably due to bug... so that all parsers behave the same,

ComparisonEngines.comInteresting article about SKU; it IS a problem for first-generation comparison sites! How to standardize product names? What about ***Free Delivery*** and ***Refurbished*** in product titles?Last year, November-06, I bought Cheetah 15K.5 SAS, and merchant http://www.directdial.com didn't know exact product name. Seagate published this SKU on their website only in April 2007!
