Re: lucene wildcard query with stop character

Thanks very much for your reply. I am having problems creating an IndexReader object for this purpose. This is the relevant code for my method: public List wildSearch(File indexDir) throws Exception { List searchResult = new ArrayList(); Directory fsDir=FSDirectory.get

Sounds you should use DBSight. Besides simple SQL crawler, you can adjust ranking by time(freshness), efficient multi-valued facet search(tagging), etc. -- Chris Lu - Instant Scalable Full-Text Search On Any Database/Application site: http://www.dbsight.net demo: http://se

Re: Options of Field constructor accepting Reader

: I was wondering why only the Field constructor which accepts a String offers : Store and Index options? I understand there might be no logic in offering : them for the TokenStream constructor, but what's wrong in Storing an input : from a Reader, that 2.3.2 does not allow it? if you want to stor

Simple Web Search

I would like to provide a simple web search of our web site. We have a lot of dynamic content, and instead of searching through the database, I would like to use some some sort of crawler to index the site. Is there one available that generates Lucene indexes? I looked into Nutch, but it loo

Hello, Thanks for your interest. Actually, it's a normal unstructured text. In the text, they might describe the number of animal or enumerate the kind of animal one by one, etc. To me, it's very difficult to resolve this. I don't have a clue until now. All comments are VERY welcome. Thanks. Re

Re: Problems understanding QueryParser + WildcardQueries

Here's your answer I think http://wiki.apache.org/lucene-java/LuceneFAQ#head-133cf44dd3dff3680c96c1316a663e881eeac35a In a nutshell, wildcard queries are not passed through an analyzer, although they are lower-cased by default. So you're indexing foobar but searching on _foobar (after rewrit

Re: Custom BooleanQuery

First, have you tried looking at bq.toString() to see what your query looks like? But from your code, you're not assigning your createTerm to anything, so your BQ is constructed from two terms on "field" that have no values. You need something like bq.add(t.createTerm("foo), Occur.MUST); Best Er

Re: Concurrent query benchmarks, with 1,2,4,8 readers

Also note, there is the contrib/benchmark source in Lucene that allows one to do many of these tests in a "standard" way, such that the results are easily reproducible. Do you actually have a situation where you would ever see 8K threads? Or even 4k? Or was this just for the purposes of t

Problems understanding QueryParser + WildcardQueries

Hi, I have a small problem regarding QueryParser and WildcardQueries. Basically, I'm indexing documents like this: doc.add(new Field("title", "_FooBar", Field.Store.YES, Field.Index.TOKENIZED)); Afterwards I expected that this query would return the document above: QueryParser parser = new Quer

Custom BooleanQuery

Hi, I'm trying to build my own query. I want to combine several TermQuery + 1 PrefixQuery in a BooleanQuery. The Code looks like this: BooleanQuery bq = new BooleanQuery(); Term t = new Term("field", ""); t.createTerm("foo"); TermQuery tq = new TermQuery(t); bq.add(tq, Occur.MUST); t.create
