escaping special characters

Hi, I followed the following procedure to escape special characteres. String escapedKeywords = QueryParser.escape(keywords); Query query = new QueryParser(content, new StandardAnalyzer()).parse(escapedKeywords); this works with most of the special characters like * and ~ except \ . I can't do a

Get BestFrequentKeywords

Hello to all, Thanks for help in advance. Example docs: 1,car, volvo, dealer, tyres 2,car, mercedes, dealer, tyres 3,car, renault, export, tyres So, if i look for car, so i would like to get, except normal results, a list of most frequent terms in result set. This would be in my example:

Re: Get BestFrequentKeywords

Look into adding Term Vectors to your fields, which will store the term frequency by document. Then you can use the TermVectorMapper to load them sorted by frequency across all the documents in your set. -Grant On Aug 4, 2008, at 7:40 AM, Martin vWysiecki wrote: Hello to all, Thanks

Range search between two different fields.

I have a search which needs to find dates which are specified in two different fields. For an example: I have a Java object with a date field that starts the time something started and another that specifies the time that something ended. I need to do a date search that the range is specified

RE: getting started

Ok, say each line is an address. So the text file would look like: 123 Water St. Somerville, GA 12345 456 Easy St. Hope, CA 45676 34 Ocean Blvd. Staten Island, NY 93843 The file would have hundreds of thousands of addresses. So the user would type 34, St in the search box and press a Search

Re: Range search between two different fields.

Could you explain your problem a bit more? It's completely unclear to me what java objects have to do with searching a lucene index. If you're extracting data from some java objects somewhere to insert in an index, then it's up to you to index them such that you can extract the information in a

Re: Range search between two different fields.

Thanks for the feedback and the quick response. The problem was a result of unclear requirements fortunately I do not have to specify the range to be between two different fields. Erick Erickson wrote: Could you explain your problem a bit more? It's completely unclear to me what java

Re: next release

I am still in trouble deleting documents. Appearently - when an indexwriter and searcher is open at the same directory - you can not delete documents with ids. to delete documents with ids you need to access indexreader which is only accessible tru the indexsearcher, thus resulting in a lock

Re: next release

yes, thats why I asked any news for release of 2.3.3. I will be using it in a production environment and a little paranoid about using the trunk. I have been waiting for this delete by query for a long time. Best, -C.B. On Tue, Aug 5, 2008 at 3:45 AM, Michael McCandless [EMAIL PROTECTED]

failed to open an indexer after about 20 queries

Hi, The indexer can't be opened after about 20 queries in linux system, but it is fine if the index is in windows  system. The indexer is the same in both systems.   reader = IndexReader.open(indexName);    //failed after about 20 queries   searcher = new IndexSearcher(reader); 

RE: failed to open an indexer after about 20 queries

Xh, We need to see a little more code her. Are you reopening the reader for each query? If so are you closing it each time? We need more information. John G. -Original Message- From: xh sun [mailto:[EMAIL PROTECTED] Sent: Monday, August 04, 2008 8:34 PM To:

Lucene excluding 'not' from search terms

As in the subject title, it seems the word 'not' is being excluded from my searches. Note the lowercase, it isn't being treated as the boolean operator 'NOT'. For example, given the query sticks not stones, it parses it as +keywords:stick +keywords:stone. Whereas if I use the query sticks NOT

Re: Lucene excluding 'not' from search terms

Hi, I guess it is with your analyzer. What is the analyzer you are using? If it is StandardAnalyzer it drops words like a, the, etc. You can use the SimpleAnalyzer and check. (I am not very sure because I am also new to Lucene :) On Tue, Aug 5, 2008 at 10:04 AM, SoupErman [EMAIL PROTECTED]
