I have one collection, 3 shards, 2 replicas, I defined route field: title,
and ID is the unique key.
I index two document with same ID and different title, I configured dedupe
chain and I can see signature is generated, but the old document was
removed by solr, please help, thanks
Hi,
Checking in again if someone can pitch in for my earlier post to this

I agree, documents may be gigantic or very small, with heavy text analysis

so it's not possible to give an evaluation here.
But you could make use of the nightly benchmark to give you an idea of

I faced these problems a while ago, but at the time I created a blog post

Hi Srinivas,
Filter queries don't impact scoring but only matching.
So, what is the ordering you are expecting?
A bq (boost query) parameter will add a clause to the query, impacting the
score in an additive way.
The query you posted is a bit confused, what was your intent there?
To boost search
I think if you have _root_ in schema.xml you should look elsewhere. My memory
is merely adding this one line to schema.xml took care of our problem.

Yes, check performance before turning on the stats cache in prod.
When we tested the LRUStatsCache in 6.6.2, searches were 11X slower.
It should be possible to do distributed IDF with little extra overhead.
Infoseek was doing that in 1995 and the patent on the technique has
expired.

You should be using docvalues on your id, but note that switching this
would require a reindex.

Hallo Bernd und Markus,
A very instructive article, by the creator of TLOG mode (introduced in 7.0,
btw):

It helped me when architecting our replication policy.
Not an easy matter, it's a
Hallo Bernd,
I see the different replica types in the 7.1 [1] manual but not in the 6.6.
ExactStatsCache should work in 6.6, just add it to solrconfig.xml, not the
request handler [1]. It will slow down searches due to added overhead.

When I performa a long running streaming expression, sometimes I get:

Hello Markus,
thanks a lot.
Is TLOG also for SOLR 6.6.6 or only 8.x and up?
I will first try ExactStatsCache.
Should be added as invariant to request handler, right?
Comparing the replica index directories they have different size and
the index version and generation is different. Also Max
Hi,
A while ago I asked the same thing here. Looking at the source javascript code
of the frontend app, I saw a 10k millisecond timeout config in httpInterceptor
inside app.js. I changed it to something much larger and results of long
queries began to show.
Hope it helps

Hello Bernd,
This is normal for NRT replicas, because the way segments are merged and
deletes are removed is not synchronized between replicas. In that case
counts for TF and IDF and norms become slightly different.
You can either use ExactStatsCache that fetches counts for terms before
scoring,

I have a scenario where I'm using filter query to fetch the results.
Example: Filter query(fq) - PARTY_ID:(abc OR def OR ghi)

Hello list,
a question for better understanding scoring of a shard in a cloud.
I see different scores from different replicas of the same shard.
Is this normal and if yes, why?
My understanding until now was that replicas are always the same within a shard
and the same query to each replica
Hi All,
I'm facing a problem with my Solr8.7.
When I do a query on my collection from the Solr UI, if the request takes
more than 8s nothing happens.
I mean, Solr UI answer a blank page. No error in log, no response, nothing
at all.
And if I do the same request just behind, the answer
Should I stop indexing new documents, or stop indexing and wait for collections
to recover?
Recently our disk got 100% full and Solr started to throw various errors. So I

freed some space but many collections went

I’ve encountered another issue that might be related to nested schema.
