RE: Problems about using Lucene to generate tag cloud..

May be you can index the set of documents in a temporary index. This index needs only one field (tag). Then you can browse the terms collection of the index and get each couple term/frequency IndexReader reader = IndexReader.open(temp_index); TermEnum terms = reader.terms();

stemming in Lucene

Hi all, Snowball stemmers are part of Lucene, but for few languages only. We have documents in various languages and so need stemmers for many languages (in particular polish). One of the ideas is to use ispell dictionaries. There are ispell dicts for many languages and so this solution is good

Re: setPositionIncrement questions

Re: Problems about using Lucene to generate tag cloud..

I registered myself just now, an interesting website. It seems crossfeeds generate a tag cloud offline hourly ? But I have a more strict time requirement. user submit a query in my website, and they may get tens of thousands of search results. I need to generate a tag cloud for all these

Controlling index file name

We use Lucene to create simple data stores that we deploy with our application. Our application also supports auto-updating and we refresh these data stores monthly. Since Lucene computes the names for the index we end up deploying new files each time while leaving the old files to continue

intuitive explanation for what seems like odd result?

I have two slightly different queries, and am filtering to return only a single unique document. The scores are very slightly different, but in the opposite way from what my (naive) reasoning would have expected. In the first case the query is text:j2ee^2.0, text:soa^2.0, text:webservic,
