Hi,
I have Lucene 1.4.3 codebase and I got Parallel Reader from the trunk along
with a few changes that need to go on top of it to make it compile.
II have 2 indexes, against which I am querying using the Parallel Reader. Most
of my queries work great. Thanks for the great work on this feature.
One index has only content and the other index has dates and basically all the
information related to the document.
I have two questions.
Question 1:
========
When I use a date filter (using the DateFilter.java) in my query, then it seems
to hang. Has anyone faced an issue with using DateFilter and Parallel Reader.
On further debugging, I found it seems to continously go through this piece of
code in FSDirectory: FSInputStream.clone method continously.
public Object clone() {
FSInputStream clone = (FSInputStream)super.clone();
clone.isClone = true;
return clone;
}
This seems to be the code path taken...
at org.apache.lucene.store.FSInputStream.clone(FSDirectory.java)
at org.apache.lucene.index.SegmentTermEnum.clone(SegmentTermEnum.java)
at org.apache.lucene.index.TermInfosReader.terms(TermInfosReader.java)
at org.apache.lucene.index.SegmentReader.terms(SegmentReader.java)
at
org.apache.lucene.index.ParallelReader$ParallelTermEnum.next(ParallelReader.java)
at org.apache.lucene.search.DateFilter.bitsForField(DateFilter.java:)
at org.apache.lucene.search.DateFilter.bits(DateFilter.java)
First of all, is it a good idea to get all the code from the trunk, instead of
just pieces to make ParallelReader work or is there a bug which I can just fix
and move on with the existing code ?
Question 2:
==========
My index 2 is expected to be dynamic, meaning will be deleted and reindexed
often. Will this not change the Doc ids? My understanding is, Parallel reader
expects doc id (Lucene internal) to be the same for it to query against these 2
indexes and return results appropriately. Is my understanding wrong?
Appreciate any help in this respect.
Thank you
