Hi all
I am playing about with the index pruning contrib package, I want to see
if it will make a faster and slightly smaller index for me. However when
I try either Carmel or RIDF methods it just ends up deleting all my
postings for the two fields of interest.
My command line for RIDF is as follows, any ideas what I could be doing
wrong ?
java -cp
./lucene-pruning-3.6.1-sz_release.jar:./lucene-core-3.6.1_sz_release.jar
org.apache.lucene.index.pruning.PruningTool \
-del title:pPsv,descr:pPsv \
-in ./index -out ./pruned-index2 \
-impl ridf -t -0.1
Hey Greg,
Sorry for a late answer ... the field spec string "pPsv" configures the
PruningPolicy to completely delete the postings, so it's doing what you
told it to do ;) The actual pruning would have happened at a later
stage, but since the postings are removed first there is nothing to prune.
If your intention was to apply pruning only to selected fields then
there is no command-line option for this in the tool - however, it's
easy to add it, because the *Policy implementations usually take a
Map<String,Number> to specify thresholds, where keys are either field
names of field:term pairs.
