RE: Wildcard search - Why can't I search for *term?

In a way, *term searches are supported - just iterate through every term in TermEnum. Unfortunately, this is a linear O(n) algorithm so it does become very slow as the number of terms in the index increases. If your index is small (eg, < 1GB), I find the search time still pretty acceptable. Other

Wildcard search - Why can't I search for *term?

As I understand it Lucene does not support wildcard search terms in the form of *term. But in my project I need to search for terms by their tails. Does anyone have a work around? Thanks. Sheldon -- To unsubscribe, e-mail: For additional commands, e-mail:

RE: Objects as search results

I also faced this problem in my project. I store two classes/types of objects in the index: topics and messages (it's a forum search engine). My very simple object/relation mapping is a class is called LuceneBridge: public class LuceneBridge { // Object --> Document mapping public Docume

Document Scoring

Hi, I've been going throught the source code, attempting to find the exact point in time where the score for each document is calculated and the methods that do this. I've ended up very confused! Methods such as IndexReader.docFreq(Tem t) which are then used by Query.scorer(...) are declared a

Re: Querying multiple fields of a index

Hi, If you are using the queryParser and the standardAnalyzer you would use a querystring like title:lucene AND summary:engine So the pattern is : Also, you don't have to explicitly put the field name if you are searching the default field. That is if title is the default field the search w

[Repost] FNFE while indexing

This is a repost of a message I posted a month ago. Hope someone can pick it up and shed some light on the mystery. Encountering an odd FNFE during indexing... 2002-03-07 14:38:56,160 [Thread-2] ERROR com.marketingbright.core.tasks.SearchIndexingTask - C:\index\_l.fnm (The system cannot find the
