There's no built in way to do this AFAIK, but I'd recommend just creating a service class or extension method to access SearchClient.Instance.Search<T> with the FilterOnCurrentSite() extension already added. Then, you can re-use that code anywhere you need to make a search with IClient. Sometimes we'll place all our queries into a SearchManager class and then have a single private generic method in there where we set some base filters, and then each method might add additional filters for what it needs.
Personally, I'm a fan of having things like this be easily visible in the code since that's less "magic", but there's probably also a way to use StructureMap / DI to make this happen globally if you really wanted.
Hope this helps,
I apologize if this has been answered already but i can't seem to locate the answer.
I am looking for a way that on every time we do a search, we apply a filter on every request. So by example, i want to filter results based on Site. Is there a way that instead of using .FilterOnCurrentSite() on every single query we have, is there a way to do this automatically on every query?
Thanks in advance.
