Hi,
I am new to lucene. Anyone please explain how to sort the numeric
values by SortedNumericDocValuesField?
I tried like this using Lucene 4.10.4:
doc.add(new SortedNumericDocValuesField("Numericdoc_price", 1L));
doc.add(new SortedNumericDocValuesField("Numericdoc_price", 15L));
..
for (A
out right ... did something go wrong?

Hi,
Could you please explain how to store the SortedNumericDocValuesField
to include in the code?

Hi,
I have one doubt. Actually I have indexed 50 documents for both
SortedNumericDocValuesField and IntField separately . Each document
consists of 49 fields. After that, i performed indexing & searching ( with
& without sorting) .
It seems DocValuesField indexes and searches the docume

Hi,
I am using Lucene 4.10.4. Is there any way to delete a term or
facetfield mapping from lucene main index which is used to refer the
categories in taxonomy. And i know once a category is added to the
taxonomy, it can never be deleted. So i am trying to remove that facet map
from main index.

Hi Shai,
i)Hope, when opening SortedSetDocValuesReaderState , we are
calculating ordinals( this will be used to calculate facet count ) for doc
values field and this only made the state instance somewhat costly.
Am I right or any other reason behind that?
store path and dimension in
SSDVF field?
Kindly post your suggestions.

Hi,
For matching documents, Is there any way to calculate mix and max
values on NumericDocValuesField ( say date field)?
*Case:*
I would like to implement it in numeric range faceting by splitting the
numeric values( from result documents) into ranges.
Kindly help me to move forward.

Hi,
I would like to enable doc values on all fields that I need to
sort or aggregate on. At search time, I am performing sort for a single
field, whether the whole doc value files (.dvd & .dvm) information are loaded
in memory or a particular field information from that file(say a single

Hi,
We are going to implement faceted search (for both string & numeric)
based on DocValuesField. For better performance, we decided to put the
SortedSetDocValuesReaderState in cache ie
*During first faceted search - new DocValuesReaderState will be opened and
"$facets" values will be loade

Hi,
Great to see DocValuesStatsCollector is available in Lucene 6.4. It
helps to compute statistics on DocValues Field. Hope, it has been achieved
using GlobalOrdinalsCollector.
My doubt is

Hi,
We have planned to implement both string and numeric faceting using
docvalues field.
For string faceting, we have added pathtraversed dimensions in drilldownquery.
But for numeric faceting , how and where can we add pathtraversed ranges during
nextlevel faceted search.?
And which is the
.java under the lucene/demo
> module... it shows how to do this.

Hi,
While working with Searcher.Search, I have noticed a difference in
their performance. I have 10 lakh documents and 30 fields in my index. I
have performed three searches using different queries in a sequential
manner. At search time, I used MMapDirectory and index is opened.

lly mostly depends on the total number of matches since Lucene needs to
