Re: Help needed Regarding classification of Text Data using Lucene..

Hi, you can have a look at the (early stage) Lucene classification module on trunk [1], see also a brief introduction given at last ApacheCon EU [2]. Hope this helps, Tommaso [1] : http://svn.apache.org/repos/asf/lucene/dev/trunk/lucene/classification/ [2] : http://www.slideshare.net/teofili/tex

I verified that the index was correct using the app Luke, tested some queries using it then replicated the results via code. It seems I need to refine the token parsing but at least I have something now. Ramon Casha On 18 December 2012 15:50, Ramon Casha wrote: > Hmm ok I got something. > > > R

Re: Help needed: search is returning no results

I converted them to TextField but the result is the same. doc.add(new TextField("text", text.toString(), Store.YES)); The search always returns an empty array. Ramon Casha On 18 December 2012 15:35, Jack Krupansky wrote: > Maybe you wanted "text" fields that are analyzed and tokenized, as o

Re: Help needed: search is returning no results

Maybe you wanted "text" fields that are analyzed and tokenized, as opposed to string fields which are not analyzed and stored and queried exactly as-is. See: http://lucene.apache.org/core/4_0_0/core/org/apache/lucene/document/TextField.html But, show us some of your indexed data and queries th

I think you need TextField rather than StringField. See also http://wiki.apache.org/lucene-java/LuceneFAQ#Why_am_I_getting_no_hits_.2BAC8_incorrect_hits.3F -- Ian. On Tue, Dec 18, 2012 at 2:14 PM, Ramon Casha wrote: > I have just downloaded and set up Lucene 4.0.0 to implement a search > faci

There's an example build file, see It's pretty outdated stuff there though. It has some flexibility for a custom document handler in order to allow full control over how a File gets turned into a Lucene Document

How many processors do you have on this system? If you are CPU bound, 100 threads is going to be 10 times slower (at a minimum) than 10 threads (unless you have more than 10 CPUs). -Yonik http://www.lucidimagination.com On Fri, Oct 23, 2009 at 2:18 AM, Wilson Wu wrote: > Dear Friend, >     I hav

Re: Help needed bubbling up relevant records with most recent date

Use a span near query to add boost for the phrases. If you only want to add boost for exact phrases (0 slop) you might want to consider using shingles. In order to add greater score for a date closer in time you can choose between a range of solutions depending on your needs. Using a functi

Not quite sure what you ask for, but I think you want to use a span near query (for adding boost to phrases) in a disjunction max query (to define weights of the different fields). karl 1 okt 2009 kl. 02.40 skrev mitu2009: Hi, I've 3 records in Lucene index. Record 1 contains healt

Kumar, you'll have to make your own documents with after parsing yourself the HTML (e.g. with Nekohtml to dom). As for the weights of tokens, supplementarily to IDF, you can do that per field, i.e. when you add a field into the document. paul Le 28-mai-09 à 12:22, Gaurav Kumar a écrit :
