Does this plugin have API for adding content stored in plugin database tables?

I’d like to know if this plugin allows me to search everything within my site.

Such as plugin content for example the “GIGPRESS” plugin (http://wordpress.org/extend/plugins/gigpress/). Will I be able to search Venue names

Eg: Venue name would be Club Hype, San Diego CA.

Will this plugin search that type of text?
