Hi,
In the past (lucene 4) I have tried to implement a simple Similarity to
only count the number of occurrences (term frequencies) into the documents,
ignoring norms, doc frequencies, boosts... It worked for some queries like
term and wildcard queries, but not for others, like phrase and range
In the past I have tried IndexSearcher with an ExecutorService to
parallelize searches on multiple segments on a SSD disk. That was with
Lucene 4.9. Unfortunatelly the searches became slower with various number
of threads in the pool, and much slower with 1 thread. There was some
overhead with

A related question: is it possible to do faceting on a SortedDocValuesField
using Collation rules? Or faceting is always case sensitive?
Thanks in advance,

Hi Lucene community!
I can successful get original doc values from fields indexed with
SortedDocValues with code like:
BytesRef bref = atomicReader.getSortedDocValues(field).get(doc);
String value = bref.utf8ToString();
But as I need to use locale sorting, I use ICUCollationDocValuesField for

Sorry, I was looking at the wrong place. Should I use BinaryPoint (
https://lucene.apache.org/core/6_0_0/core/org/apache/lucene/document/BinaryPoint.html)
?

Hi all,
Lucene is able to index generic n-dimensional points for efficient
similarity or nearest neightbors search? I have looked at spatial package
in the past but seems it is specific to geo points? The use case is to
index image feature vectors to search for similar images in a corpus.
Hi Lucene community,
Is BinaryPoint limited up to 8 dimensions?
Thanks,
Luis

Hi all,
Lucene 7 still deletes and re-adds docs when an update operation is done,
as I understood.
When docs have dozens of fields and one of them is large text content
(extracted by Tika) and if I need to update some other small fields, what
is the best approach to not reindex that large text
, you might find some of the

Hi Lucene community,
Our users could do very heavy searches and they are able to change the
sorting criteria multiple times after getting the results. We collect all
of them, this is important for our use case, disabling scoring if the
result size is too large to make the search faster. Currently
