Amend ContentSearch settings to a single index?

Question

I have a bunch of custom indexes and I need to finetune only 1 of them, not affecting the others. Let's say, I want to change ContentSearch.Update.BatchSize, is there a way to apply this setting for 1 particular index?

Answer 1

No, that's not possible out of the box.

SolrContextFactory class, which is responsible for creating IProviderUpdateContect implementation object, checks if batch mode is enabled for indexing, by checking

`Settings.GetBoolSetting("ContentSearch.Update.BatchModeEnabled")`

If it's not enabled, it creates an object of SolrUpdateContext.

And if it's enabled, it creates an object of SolrBatchUpdateContext class with batch size read from configuration - ContentSearch.Update.BatchSize.

There is no place there for getting batch size for a single index, unless you create a new implementation of AbstractContextFactory and override GetUpdateContext method to return index-specific batch size.
