Have you considered using bi-grams and tri-grams? It might be useful
indexing with NgramFilter and then searching for N-grams through the text.
You could also count the number of times a particular document consists of
"Car Insurance Rate" for term-frequency etc.

Peter,
CharTokenizer may be the cause of the problem.
It is the parent Tokenizer of WhitespaceTokenizer
which is used by WhitespaceAnalyzer and it
has 255 bytes buffer.
How about using KeywordAnalyzer instead of WhitespaceAnalyzer?
Thanks,

I have just joined this user group, but I probably will be asking questions /
contributing for a while now as I am starting to work on a product which will
use Lucene exclusively.

hi Rajesh,
thanks for the reply. i'll go ahead with the new method as you suggest.

have you tried the WorldNet ad-on? You can easily expand the query with

I have some really long chemical names that I am storing in an index and
it looks like they are being split into two terms. Is there a way to
increase the max term length?
Here is an example:

;hormonereleasing factor pig679010N
I would suggest you to look at papers on local/global document analysis. One
of the approach is to get a set of terms which co-occur with the query term
say "insurance". From the initial query they select the top 'N' documents
and compute the co-occurrence of other terms (usually those having high

I think you should build a type of domain specific dictionary first. You

You have to recursively traverse the directories using something like...(in
Java)
void indexDocs(String file){
if (file.isDirectory()) { // if a directory
String[] files = file.list(); // list its files
for (int i = 0; i < files.length; i++) // recursively index them

Actually, the relevance is the primary sort, and the date is the secondary
sort. Still the same sort problem. Any help will be greatly appreciated.

My primary sort is by date and my secondary sort is by relevance score.
The Hits.getScore() method returns the score by 7 digits to the right of
the decimal point. Therefore, If I round to only 2 decimal points in the
display, the underlying 7 point score will be different in the sort.
Example:
Actually I get the same result with CJKAnalyzer like with StandardAnalyzer.

When using the TermEnum method won't the terms be analyzed i.e. split in
