Hello, Emir:
Thank you for your reply.
I do understand that the frequency of creating searcher depends on how much
realitime-search is required.
As you advise me, I have checked a soft-commit configuration.
It is configured as:
${solr.autoSoftCommit.maxTime:-1}
If I am correct, I have not set autoSoftCommit, which means autoSoftCommit
does not create a new searcher.
Next, I will take a look at my explicit commit.
I am curious about what you say "warming strategy."
Is there any good resource to learn about tuning warming up?
As far as I know about warming up, there is two warming-up functions in
Solr.
One is static warming up, which you can configure queries in solrconfig.xml
The other is dynamic warming up, which uses queries from old cache.
How should I tune them?
What is the first step to look at?
(I am kinda guessing the answer can vary depends on the system, the
service, etc... )
Sincerely,
Kaya Ota
