Islandora Advanced Search Module Ajax does not work if no facets are used on the search page.

[nigelgbanks]

Current theory is that the following files:

https://github.com/Islandora/islandora/blob/8.x-1.x/modules/islandora_advanced_search/islandora_advanced_search.module#L48-L59

Which override ones provided by the Facets module contain the required code for triggering Ajax requests. If no facets are used the file is not included.

The logic should be moved out to a separate file that gets included via another method that does not rely on facet blocks, but rather the search view.
