Re: Highlighter doesn't highlight wildcard queries after updating to 2.9.1/3.0.0

ymore like Lucene 2.3, and returns nothings renderable, I stopped rewriting and to my surprise, highlighter worked with prefix, or other queries. It was also needed to add lucene-memory contrib library (which is referenced by WeightedSpanTermExtractor) to prevent exception (NCDFE). Mohsen Mohsen

Highlighter doesn't highlight wildcard queries after updating to 2.9.1/3.0.0

After updating to 2.9.x or 3.0, highlighter doesn't work on wildcard queries like "abc*". I thought that it would be because of scoring, so I also set myIndexSearcher.setDefaultFieldSortScoring(true, true) before searching. I tested with both QueryScorer and QueryTermScorer. In my custom highligh

Doesn it make sense cache IndexReader?

Hi, I have a set of indices in different languages (very smal indices: on average each index directory has 10,000 documents, which has an overall size of less than 2mb). I want to know if this is a good idea to cache IndexReader (once opened) somewhere and further reuse it? My application is singl

User Defined Matcher

Is it possible that I inject my own matching mechanism into Lucene IndexSearcher? In other words, is this possible that my own method be called in order to collect results (hits)? Suppose the case that I want to match - for example - "foo" with both "foo" and "oof". Thanks in advance, Mohsen. --

Leading and trailing wildcard together

Hi, I've noticed that from Lucene 2.1 leading wildcard can be enabled using QueryParser.setAllowLeadingWildcard(true), however I wasn't able to search for *Foo* (while "?Foo*" and even "?*Foo*" works). Is it possible to have leading and trailing star wildcard together? Thanks. -- View this messa

Error Tolerant Query Parser

Sorry for dual posting. I've just inadvertently submit form before writing the body :) Is there any error tolerant query parser ever written for Lucene? What is the way websites use for advanced searching with Lucene? -- View this message in context: http://www.nabble.com/Error-Tolerant-tf35240

Re: Emulating Pages Search

This is possible, but the problem here is performance. Why is it not possible to support pagination in a more efficient way? Suppose, a Searcher looks through Documents and find the matching ones. Theoretically, it can stop searching when the result hit number gets more than a threshold. Searcher

Emulating Pages Search

Hi, Is there a way to do emulate paged search in Lucene? I can use the following peace of code for returning the first page (10 items in each page), but don't know how to navigate to the next page :-) IndexSearcher is = new ... ... TopFieldDocs tops = is.search(query, null

Matched Query Part in Hit Object

Hi, Is there a way to find the matched part of query string in the Hit object? Lucene's Hilghlighter module does part of the job, highlighting the matched word in the result document, however it doesn't give the effective keyword in query string. For example, suppose I have a query: "lorem OR elit
