Need Pipeline in Coveo for Sitecore
Is there a pipeline which I can use to run a process to prepare data before the individual item processing begins?
Coveo for Sitecore doesn't have a specific pipeline that runs at the beginning of the indexing process of a batch of items (rebuild, re-index tree…). However, each time an indexing command is sent by Sitecore for a single item or a batch of items, Coveo for Sitecore will synchronize its configuration with CES. Part of this synchronization is for the CES field sets. There's a pipeline called
coveoBeforeUpdateFieldSetPipeline that is run to allow the field set to be modified. You could create a processor for this pipeline and run your process in it without modifying the field set.
