Look for strange encodings -- tokenization

Hi all, I'd want to know the best way to look for strange encodings on a Lucene index. i have several inputs where input can have been encoded on different sets. I not always know if my guess about the encoding has been ok. Hence, I'd thought of querying the index for some typical strings that wo

FieldCacheImpl mistake?

Hi guys, I have been diving into the FieldCacheImpl code. I have seen sth on actual version: Revision 488908 - (view) (download) (annotate) - [select for diffs] Modified Wed Dec 20 03:47:09 2006 UTC (8 weeks ago) by yonik File length: 13425 byte(s) that I wonder if it's not totally right, or if

FieldCacheImpl not "extendible"

Hi, I have been diving into the code and I don't see why the class FieldCacheImpl is not extendible. It is not defined as a public class... though, I would like to be able to subclass it to change a slight bit. Why is it defined like that? Thanks -- View this message in context: http://www.nab

Extending Query, Weight, Scorer

Hi, I have created a Query that works for numerical max-min ranges, that may work for any Field specified. I have done that by extending Query, and creating own Weight and Scorer subclasses as well. So it works ... but I have problems when setting min or max boundary to 0: In this case, those ent

deviations

Hi, I would like to query results, regarding results. For example, get those results whose field "size" is 2 standard deviations from the median. It looks like sth I should do myself, processing results first, getting the median, and then calculate that threshold and perform a new query. Is it h

query problem: grouping "with same field"

Hi all, First of all thanks for this forum, I have read stuff that helped me a lot. Second, I would like to query a Lucene index in this way: I want to do operations on groups of entries. These entries I want them to be grouped by a field, (called websiteid), so the queries will only go to those

HI guys, I've read on http://www.nabble.com/Using-NOT-queries-inside-parentheses-tf1234775.html#a3272973 this forum about the problem of using, for example, only a prohibit search such as -description:plot I really would like to get this done on a good manner, I am constructing queries where e

Problem with lucene.

Hi there, this is my very first post at this forum... please be considerate :) Well, i have a problem when sending a query such as: +description:< Once the query is parsed, it returns me the empty String, which means the String "<" that i want to search for on the field description is ignored.
