The number of documents will be 3 times as each post/document has 3 different language versions.
(1) GSS only gives you 1000 records in search result and we give your clients all.
(2) GSS doesn’t allow you to control the order of their results, whereas we allow you to have that control from your SearchIQ account.
(3) GSS provides predefined search/promote box, we don’t have that yet.
(4) Since you are using our javascript-based product, your site is indexed every 24 hours and I think Google is doing similar.
(5) GSS doesn’t provide you a big size thumbnail as we do.
(6) Our support team should be way more active when you have questions related to our service than google.
There are two things you can check:
(1) The sites you want to cross search needs to be indexed and put under the same group.
(2) Make you have turn on “Display results from Linked Site” on Dashboard.
