Searchanise Not Searching Right?

Has anyone come across this issue? We have activated Searchanise, but it isn't fetching all the products it should when searching

When we disable Searchanise the search works properly and brings back the right results, but when we enable Searchanise it either brings partial or no results at all.

Below are some example of having Searchanise enables and the results that are returned:

This vendor store has four products with 'block' in the title:

, but when you search the marketplace for 'block' only two of the four are in the search results:

Similarly, this vendor store has 44 Products with the word 'switch' in the title:

, but when you search for 'switch' it returns ZERO results?

This seems weird. Any thoughts?
