Build an index which allows me to broswe by category.
-----------------------------------------------------

         Key: LUCENE-477
         URL: http://issues.apache.org/jira/browse/LUCENE-477
     Project: Lucene - Java
        Type: Task
  Components: Index  
    Versions: 1.4    
 Environment: JDK 1.4, Windows 2003, Tomcat 5.0.28
    Reporter: Mark Dos Santos


Hello there,

I have a collection of documents that I am using lucene to build an index for, and then I
have a jsp app to search my documents. This all works great. I believe lucene is such an amazing
product, but thats a whole other topic. Anyway, maybe it's my lack of experience in building
indexes, but I am have trouble coming up with an index that kind of mimics verity's parametric
index.  You see my documents all have a category path (I have over 50,000 docs).  A document
can be at any level of the category path, and that same path can have many different documents.
IE. Document x, has a category path USA//New Jersey//Trenton//09890 and Document y has a category
path USA//New Jersey//Trenton//09890.  

Basically, I would like to build an index using lucene, where when I search, if my results
were to bring back those two documents, I would like to retrieve the distinct category path
for those two documents.  Of course I can loop through and build a vector with only the unique
paths that come in the search results, but that obviously would take to long when I get lets
say 10000 results from my search.

So the question I guess is, how can I build an index that would facilitate this functionality
for me.  If anyone has any suggestions I would greatly appreciate it.

Thanks,
Mark
