RE: Announcement: Lucene powering CNET.com Product Category Listings

Zach, Let's simplify the issue to displaying counts for a single "Attribute" -- manufacturer. Imagine that the main search you are executing is "+category:cameras +price:[0 to 10]" and you want to sort it by name. You also want to display the counts per manufacturer for all products that match

Re: custom sort

: What I'm doing now is taking the whole resulting document collection, : iterating through it and manually moving these 10 documents to the front : of the collection. This is slow and ugly. I was hoping there might be : a slicker way to do it as part of the actual sort. I will play around : wi

Problem With RAMDirectory.

Hi, I'm using the Lucene demo to create an index for 10 text files, just for testing. I use the demo to do searches on the created index, and all seems well. I want to perform the search via an applet, for reasons not relevant to the problem I'm having. I zip up the three files in the index so the

Re: custom sort

I had to do something similar, but I plan on re-writing it into something more elegant. I hope this helps give you some ideas. 1. Create a QueryFilter on only those items that matched the criteria (have a required clause in your boolean query) 2. Create a BitFilter which takes a BitSet from step

Re: custom sort

Actually in this case I am sorting by score already but I'm not sure if that helps. Regardless of how I do my primary sort, I want to tweak the results such that some hardcoded number of documents that match some criteria get pushed or frontloaded to the top of the results. For instance think

Indexing source files

Hi I'm quite new to lucene, and I'm looking for information, how I can start implementing a search engine for code completion, phpdoc hovering etc. Currently I'm using an approach similar to ctags: http://ctags.sourceforge.net/, which isn't very fast in the startup time for large projects. For the

Re: Announcement: Lucene powering CNET.com Product Category Listings

Nice write up. One other nice thing I noticed is you seem to sort numeric attributes numerically instead of alphabetically e.g. here: http://reviews.cnet.com/4566-3156_7-0.html?filter=500193_5314692_ see the 3rd col, "Find by max speed", and note that has has choices in this order: < 2

Using one physical lucene index for multiple projects

Hi, I've about five different projects which would need to access a lucene index for searching. The projects are completely unrelated to each other however it's all about the same: indexing HTML documents. Since all these projects are also runnig inside the same hosting company, I thought ab
