Sharding always adds overhead, which balances against splitting the
work up amongst several machines.
Sharding works like this for queries:
1> node receives query
2> a sub-query is sent to one replica of each shard
3> each replica sends back its top N (rows parameter) with ID and sort data

There isn't any real support for joins in Parallel SQL currently. I'm
surprised that you're having some success doing them. Can you provide a
sample SQL join that is working for you?

Hi,
To satisfy one use-case, I need to apply WordDelimiterFilter with
splitOnCaseChange
with 0 once and then with 1 again. Are there some downsides to this
approach?
Use-case is to be able to match results when indexed content is my.camelCase
and search query is camelcase.
the reason why JOIN works is because of the Calcite framework. The parallel
sql features leverages Calcite, which implements all the sql features, all
you need is to provide the way for calcite to get the collection/table, in
solr this is done by the SolrTable.java (package
org.apache.solr.handler.
I am trying to find a way to grab unique values based on a group. The idea
would be to group by an id and then return that groups value.
Query params fl=valueIwant+myID&group=true&group.field=myId&q=:

"myID": {

Hi
Been using Solr on a project now for a couple of years and is working well.
It's just a simple index of about 20 - 25 fields and 7,000 project records.
Now there's a requirement to be able to search on the content of documents
(web pages, Word, pdf etc) related to those projects. My initial t
Why not just specify preserveOriginal and follow by a lowerCaseFilter and
use one wordDelimiterFilterFactory?
Best,

Hi all,
I'm struggling with an old class that extends CustomScoreQuery.
I was trying to port to solr 8.5.2 and I'm looking for an example on how to
implement it using FunctionScoreQuery.
Do you know if there are examples that explain how to port the code to the
new implementation?

I am doing that already but it does not help.

Consider something other than WhitespaceTokenizer. In this case
the tokenizer would split on the period and it’d work. I don’t know
whether that would fit the rest of your problem space or not though.
But to answer your original question, no there’s no a-priori reason you
can’t have WordDelimiter(
For the record, it is not just Solr7.4 which has the problem. When I start
afresh with Solr8.5.2, both symptoms persist.
With Solr8.5.2, tlogs accumulate endlessly at the non-Leader nodes of the
Source SolrCloud and are never released regardless of maxNumLogsToKeep setting
And with Solr8.5.2, i
Even though same document indexed over and over again due to incremental

Do I miss any configuration to make optimization occur by internally ?

Updated documents are marked as deleted in the
old segment and added to a new segment. When
commits happen, merges occur and only then is the
space occupied by the deleted document reclaimed.
Which segments are merged on commit depends
on a number of factors.
Unless you can prove the extra space

Thanks Erick for the details and reference to understand better about merging
segment stuff.
When I compare performance of uninterrupted/optimized ( segment count 1)
collection for search request vs (indexing + search) in parallel going on
collection performance is 3 times higher,
for example
That seems high. It can be tricky to get tests. Are you running with
some kind of test runner? Do you have, say, 3-4 thousand queries
you run? Are you running the tests after warming the searchers?
Also, if you have indexed down to one segment, _then_ tried
adding docs and measuring you are not ge
