Re: What is the best file system for Lucene?
Hi Sanyi Could you try XP on your desktop - that would take some variables out. The problem is that you are comparing OS, as well as filesystems, as well as different hardware configs. Also, unless you take your hyperthreading off, with just one index you are searching with just one half of the CPU - so your desktop is actually using a 1.5GHz CPU for the search. So, taking account of this its not too surprising that they are searching at comparable speeds.

Re: Lucene scalability, performance
Hi Venkat If you want to go against just html pages (maybe with Dublin core tags) then Swich-E isn't too bad, but it wont be as portable as Lucene plus it doesn't seem to be as nearly as active on the development side as Lucene (so you'll get less support in the event of problems). Swish seems easy to install & index against just html pages. If you want something a bit more capable, or if you are going against structured text files / databases / etc then choose Lucene everytime. Performance, you'll find that Java Lucene will compare well with C / Perl Swish, and for your volumes there shouldn't be any problems with Lucene.

Re: Stemming Oddness
Hi Yousef
You are not doing anything wrong - its just how the Porter stemmer works!
The problem with Porter is that it tries to do everything in a purely algorithmic way
- which doesn't cater for irregular conjugations etc.
Don't worry too much though, as long as you do the same stemming on the query string
as you did while indexing - you should be able to find what you are looking for but
can have some issues with trailing wildcards.
If you want a better stemmer, look for something that has a dictionary as well as
algorithmic rules - a quick one that is readily available is Kstem which while not
perfect I think is quite a bit better than Porter.
You can get the source code (Kstem.jar) from the floowing website:
http://ciir.cs.umass.edu/downloads/
For more info on Kstem see the paper by its designer Bob Krovetz at:
http://ciir.cs.umass.edu/pubfiles/ir-35.pdf

Pete

Re: PorterStemfilter
Hi David I like KStem more than Porter / Snowball - but still has limitations although performs better as it has a dictionary to augment the rules. Note that KStem will also treat "print" and "printer" as two distinct terms, probably treating it as verb and noun respectively.

Re: PorterStemfilter
Hi George There are lots of problems with Port stemmers, not great for English but get worse for other languages. If you look at: http://snowball.tartarus.org/demo.php You'll see the Snowball demo - this is basically another instance of Porter. If you enter "print" and "printer" and submit then the results will be "print" and "printer" - hence showing the the Porter stemmed versions are the same as the originals. Therefore they are both distinct terms in their own right and searches on one will not hit the other.

Re: Out of memory in lucene 1.4.1 when re-indexing large number of documents
Hi all Reading the thread with interest, there is another way I've come across out of memory errors when indexing large batches of documents. If you have your heap space settings too high, then you get swapping (which impacts performance) plus you never reach the trigger for garbage collection, hence you don't garbage collect and hence you run out of memory. Can you check whether or not your garbage collection is being triggered? Anomalously therefore if this is the case, by reducing the heap space you can improve performance get rid of the out of memory errors.

Re: Using MySpell iso the Snowball Analyzer
Hi Aad Use the stemmed result as what you index, but then also remember to stem the query terms as well - you need to do the same on the way out as on the way in.

Might want two demos, one for Unix environments and one for Windows. Most users will want a fast start that they can copy and adapt.

Re: RE : Parsers
Hi Victor Thanks. In the past I have used the Inso OutsideIn filters and found them very good; however I'd like to come up with a pure Java solution, so if there is a Java equivalent to the Inso filters I be grateful for any details. Failing that, I thought that I'd go for individual parsers initially using the file extensions to select the correct parser but in the future adding a file type recogniser for files without extensions. Hence my request for anyone knowing of good parsers particularly for the most common formats. That being said, has anyone come across a Powerpoint parser?
