My site have five catalogs and each time i ran a job import to import new data for per catalog and then i call the
method BuildIndex(false) in order to incrementally updates the index
This method will index all catalogs but i don't want to index all of them, i just want to index specific catalog
So, is there any way to custom index by specific catalog?
There is no built in way to do it. however if you really want to, to can extend BaseCatalogIndexBuilder, override BuildIndex to only build index of your special catalog, then register it as the indexbuilder in Mediachase.Search.config.
It's not trivial, however.
