I see, thanks, Erick! I will change some architecture of our application because an IndexWriter will be kept open when program is running. Best Regards. jacky - Original Message - From: "Erick Erickson" <[EMAIL PROTECTED]> To: Sent: Thursday, September 07, 2006

Highlighting a PDF document, last time I looked (quite a while ago), involves supplying an xml file that describes offsets for highlighting. You can specify the file in the URL. You can also do simple highlighting by passing in a list of words to be highlighted, but this does not even catch min

Thanks for the quick response Erik. I will be getting my LIA book back very soon, I forgot it at a destination :-( Lets assume, there is a document called "hello.pdf" and it has the content "this is hello.pdf. It uses Acrobat" When I perform a search for "Acrobat", i want hello.pdf to show up, a

Re: Highligher Example

There are test cases in the Highlighter codebase that exercise it and show its use, as well as a few examples of it in the "Lucene in Action" codebase. These examples output plain text with some prefix and suffix surrounding the highlighted terms. Highlighting text in a PDF is possible,

Re: best way indexing user queries

Discussed before, it's more relation db task than lucene. Simple approach is to get a list of terms from your queries and store relation document - query - terms. I have around 1.6e10 query-terms in postgreSQL and with proper index select takes around 0.6 ms (clustered vacuumed analyzed), 300

Re: Indexer large file and hi performance indexing

Here's another approach that I *think* will work... Remember that opening an IndexReader takes a snapshot of the index, and later additions aren't visible until you open a new index reader. So, at some point you have an FSDir index only, and your program starts. You open your (shared) reader to

What's the .toString on the query it parsed to? Keep in mind that "*" isn't the proper regular expression to match everything - it would be ".*" or some other pattern. Erik On Sep 7, 2006, at 7:41 AM, Luke Tan wrote: Hi, I am using code in http://mail-archives.apache.org/mod_mbo

Re: Atomic index/search for a phrase

A single TermQuery is surely the fastest query of all. But, what are you really trying to do? It is not generally useful to index things untokenized except for precise key-like fields but not for full-text ones. Erik On Sep 6, 2006, at 11:51 PM, Venkateshprasanna wrote: Whic

Did you check POI javadocs? Look for org.apache.poi.hslf.extractor.PowerPointExtractor. It's one of the most straightforward classes from POI as far extracting text for indexing is concerned. -Gopi On 9/7/06, Venkateshprasanna <[EMAIL PROTECTED]> wrote: Is there any filter available for extra

Actually, latency is not possible. Do you think it is possible to tune the fswriter to flush into the file system each N elements (using the maxMergeDocs and co) and use "for each docs of the RAMindexer (addDocument to the FSindexer)"? What about performances? -Message d'origine- De :
