RE: Range Query
Range queries use a lexicographic (dictionary) order. So, assuming all your values are positive, you need to ensure that the integer part of each number has a fixed number of digits (pad with leading 0's). The fractional part should be fine, although 1.0 will follow 1. If you have negative numbers you need to pad an extra 0 on the left of the positives, start the negatives with -, and invert the magnitude of the negatives (so they go in the other order). Your actual example below should work as is, except that 10 will not be in the range since 10.00 is strictly after 10. However, this won't work without the padding assuming you have any prices with at an integer part of other than exactly two digits (e.g., 10 is before 6, but after 06).

Unfortunately (for you), my Arabic Analyzer for Java (http://savannah.nongnu.org/projects/aramorph) is GPL-ed. Does Arabic really require a stemmer as well (some of the reading I've seen on the web would suggest that a stemmer is almost a necessity with Arabic to get anything useful where it is not with other languages).

using optimize and addDocument concurrently.
Hi, My basic question is whether it is possible to continue to add documents to an index in one Thread while running a long running optimization of the index (approx 30 mins) in another thread. I'm using Lucene version 1.4.2. The concurrency matrix at http://www.jguru.com/faq/view.jsp?EID=913302 shows that if you use the same IndexWriter object you can do concurrent writes and optimization. When I try it in my program the addDocuments wait until the optimization has finished, so in this respect it is Thread safe, but the operations cannot be performed at the same time. Our problem is that the index needs to be continually kept up to date with new news articles, but also needs to be regularly optimized to keep it fast. If I cannot update and optimize one index at the same time the best way I can see of doing this is maintaining multiple identical indexes and offlining, optimizing, letting them catch up-to-date and re-onlining them. Does that sounds best to you? Thanks a lot in advance Steve

MultiSearcher object question
I've just indexed over 600,000 documents (index size = 12GB) and have a simple servlet to search the index. I am using the MultiSearcher object (I will add more indexes in the future) in a servlet to test searching. I have noticed that the instantiation of my MulitSearcher object is taking about 5 seconds. As a solution, I have created the MultiSearcher object and stored it in the Application context so I create it once and access it subsequent times. My question is, is this a recommended practice? If I have 1000 users concurrently searching, will this approach cause problems? What do others do in web applications using the MultiSearcher object? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: using optimize and addDocument concurrently.
Steve, The behavior that you descibe is as expected. I have tackled a similar problem to yours by creating a proxy object that acts as a gatekeeper to all IndexReader, IndexSearcher and IndexWriter operations. With fully synchronized access to all methods of the proxy you will not run into any problems. Everytime I need to perform something with the writer, I close the searcher etc. As to regular optimization I tend to reindex now and again with a completely seperate writer and replace the index by moving it to the new location. This BTW has also become a method in my proxy object. Hope this helps, Cheers, Aad Hi, My basic question is whether it is possible to continue to add documents to an index in one Thread while running a long running optimization of the index (approx 30 mins) in another thread.

Re: Range Query
That is exactly right. It is searching the ASCII. To solve it I pad
my price using a method like this:
/**
* Pads the Price so that all prices are the same number of characters and
* can be compared lexigraphically.
* @param price
* @return
*/
public static String formatPriceAsString(Double price) {
if (price == null) {
return null;
}
return PRICE_FORMATTER.format(price.doubleValue());
}
where PRICE_FORMATTER contains enough digits for your largest number.
private static final DecimalFormat PRICE_FORMATTER = new
DecimalFormat(000.00);
When searching I also pad the query term. I looked into hooking into
QueryParser, but since the lower/upper prices for my application are
different inputs, I choose to handle them without hooking into the
QueryParser.
