Multisite search limitations
There are a few limitations with the search engine when using a multisite installation.
- Do not use category/term exclusions
- Do not use category/term selectors on the frontend
Categories and terms with equivalent names across the multisite network have different ID's. Therefore it's not possible to properly display and exclude them.
- Do not use custom field filters on the frontend, unelss you know that the custom field exists on each site
Some custom fields might exist on one site, but not on the other. Use custom field filters only if the affected custom field exists on each site.
