About "join.search" in 3.4 version.

Hello all, Now, I find there is a "org.apache.lucene.search.join" function in Lucene 3.4 version. But I found no demo for "join" function in the source code package: "lucene-3.4.0-src.tar". Now I have some articles, which could be modified by editors, like this relationship: an article : modify

Its a complex situation. We didn't know what did you change. I suggest you to compare/diff your code with offical version. Regards, Mead On Tue, Oct 18, 2011 at 1:13 AM, Zeynep P. wrote: > Hi, > > I am having a weird experience. I made a few changes with the source code > (Lucene 3.3). I creat

Re: How can i search lucene java user list archive?

Have a look at http://search-lucene.com/ where you can search Lucene mailing list archives (user, dev, common) its web site, wiki, source code, jira, etc. as well as the same types of data for Solr, Nutch, and so on. Otis Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch Lucene eco

Re: About "join.search" in 3.4 version.

I don't think the new join package in Lucene 3.4 will work for this case; you need more general join implementation, which eg Solr and ElasticSearch have implemented. Generic join hasn't yet been factored out into Lucene (but I think it really needs to be... any volunteers!?). Lucene's join packa

Return Lucene field name when a query is matched

Hi, I was given a task to investigate whether it is possible to return Lucene field name when a query is matched. At the moment our application returns the usual matched docs, but the new requirement would be to also know which field matched the query (e.g. found in title, header, etc.). We use

Re: Return Lucene field name when a query is matched

Re: About "join.search" in 3.4 version.

Thank you, Mike. Are you sure the 'Solr' has implemented 'Join' function. I just skims through some tour guids about Solr, and not sure about that. Appreciate you very much. I figure out another way to handler this problem. Our system also has duplication of these articles and the records(about wh

Re: Return Lucene field name when a query is matched

you description was not clear. a query will return lots of results, so every item will be different on matched field name, if you use Boolean_OR to query. if you use boolean and, then every field will match. Regards, Mead On Thu, Oct 20, 2011 at 11:22 PM, Ian Lea wrote: > You can work it out

Now I have create a filter by override "DocIdSet getDocIdSet (IndexReader reader) throws IOException ". It works nice, but I feel anxious about the efficiency. The* limit[]* would contain one hundred thousand article_id inside(10,000), and fetech one thousand articles by querying keywords on conte
