Searching Blog content thru Ajaxsearch?

Unable to search the blog content through the default AjaxSearch snippet.

When I put certain texts from the blogs that I created in the Ajaxsearch input field, it does not return any result.

Do I have to pass specific parameters for this ?
Or is it that, AjaxSearch snippet does not work for blogs and comments ?

AjaxSearch search in the main "modx_site_content" table fields and in "modx_site_tmplvar_contentvalues" value field. It doesn’t search in the comment table added by the jot snippet. For more information about sql search you can read SQL behind the scene

Thanks.
