NO.the app creates the index in a folder and I run the query in that
folder.
For example if I decide to create the folder in /home/marco/testIndex
,obviously I run the query on /home/marco/testIndex
if I decide to create the folder in /home/marco/RDFLUCENE ,obviously I run
the query on /home/marco/RDFLUCENE
But I ALWAYS obtain no results.
In order to understand how tomcat works with lucene I made an experiment: I
deleted all files in the index and I tried to run the query in the empty
folder and It fails with:
no segments* file found in org.apache.lucene.store
It means that Lucene recognizes the index (when it isn't empty) but on the
webapp It obtains no result
