One last thing, be sure to log only when a user clicks on a result
and in Hadoop document_id will be a key in the map phase.
Lucene related steps are the same.

A more advanced version could store previous result

It's more expensive at index time, has a bigger storage requirement and
is slower than in-memory but should give the desired functionality.

Utilizing "user feedback to improve search results" with clickstream

You might be able to set that Field to indexed, but not

For someone trying to get work done, use incremental updates to
one local index first. Then explore writing to multiple indexes and
reading them using MultiSearcher.
Afterward, use HTTP-based updates/requests with Solr to scale out.
Hope that helps.

Hello,
I just got this working in three or four steps:
1. goto http://www.apache.org/dyn/closer.cgi/lucene/java/
2. click on any of the mirrors and download "lucene-2.0.0.zip"
3. unzip into preferred directory (step not shown), then use jar to
look at snowball items:
jar tvf /opt/lucene-2.0.
Another solution is work with plain java dates and calendar objects,
convert into Lucene strings
using DateTools (resolution day) then query this field with two
RangeFilters using ChainedFilter.
You will never get the BooleanQuery error.
