Show result in current site using GLOBAL SITE SEARCH


I'm using WordPress multi-site, with global-site-search + post-indexer.

I have 1 main site and around 5 child sites. If I make a search in a child site, the result is given in the main site. I need to show the result in the current site, for example if the search is done in child site 3, the result must be given in that site, not in the main site.
