You can get the size of the taxonomy by calling taxoReader.getSize(). What
does the 28K of the $facets field denote - the number of terms
(drill-down)? If so, that sounds like your taxonomy is of that size.
And indeed, this is a tiny taxonomy ...
How many facets do you record per document? This a
If I am counting correctly, the $facets field in the index shows a count of
approx. 28k. That does not sound like much, I guess. All my facets are flat and
the FacetsConfig only defines a couple of them to be multi-valued.
Let me know if I am not counting the taxonomy size correctly. The

Nothing suspicious ... code looks fine. The call to FastTaxoFacetCounts
actually computes the counts ... that's the expensive part of faceted
search.
How big is your taxonomy (number categories)?
Is it hierarchical (i.e. are your dimensions flat, or deep like A/1/2/3/)?

Hi,
Thanks for your response. It does sound pretty bad which is why I am not sure
whether there is an issue with the code, the index, the searcher, or just the
machine, as you say.
I will try with another machine just to make sure and post the results.
Meanwhile, can you tell me if there is an

40 seconds for faceted search is ... crazy. Also, note how the times don't
differ much even though the number of hits is much higher (29K vs 15.1M)
... That, w/ that you say that subsequent queries are much faster (few
seconds) suggests that something is seriously messed up w/ your
environment.
Hi,
Thanks again!
This time, I have indexed data with the following specs. I run into > 40
seconds for the FastTaxonomyFacetCounts to create all the facets. Is this as
per your measurements? Subsequent runs fare much better probably because of the
Windows file system cache. How can I speed thi

Correction on [4] below. I do get doc/pos/tim/tip/dvd/dvm files in either ase.
What I meant was the number of those files appear different in both cases.
Also, does commit() stop the world and behave serially to flush the contents?

Hi Shai,
Thanks for the response. Appreciated! I understand that this particular use
case has to be handled in a different way.
Can you please help me with the below questions?

Hi
Currently there's now way to add e.g. terms to already indexed documents,
you have to re-index them. The only updatable field type Lucene offers
currently are DocValues fields. If the list of markers/flags is fixed in
your case, and you can map them to an integer, I think you could use a

Hi Shai,
Thanks so much for the clear explanation.
I agree on the first question. Taxonomy Writer with a separate index would
probably be my approach too.
For the second question:
I am a little new to the Facets API so I will try to figure out the approach
that you outlined below.
However, t

You can check the demo code here:
https://svn.apache.org/repos/asf/lucene/dev/branches/lucene_solr_4_8/lucene/demo/src/java/org/apache/lucene/demo/facet/.
This code is updated with each release, so you always get a working code
examples, even when the API changes.

Hi,
I am evaluating Lucene Facets for a project. Since there is a lot of change in
4.7.2 for Facets, I am relying on UTs for reference. Please let me know if
there are other sources of information.
I have a couple of questions:
1.] All categories in my application are flat, not hierarchical.
