Search Box ability to search for Keywords

Hello there,

I am new to GeoDirectory and right now trying to reverse engineer this site https://opportunity-funds.com/funds/ . Well, to be precise my main focus is to make the same search bars and main menu elements.

In summary I would like to have 3 directories represented with 3 different tabs in the main menu and those 3 directories i.e. project directory, funds directory & service providers directory should have 3 different search bars with 3 different search functions fund type, fund size and keywords seen here https://opportunity-funds.com/funds/

Can someone please explain in layman’s terms how can I create the same menu and search boxes or at least confirm if my understanding of this problem is correct. I think that if I grasp the basic idea of just one example I’ll be fine with others.

I went through
https://wpgeodirectory.com/support/search/search+bar+short+code/ and https://wpgeodirectory.com/support/topic/adding-a-custom-field-in-main-search-bar/ and this https://wpgeodirectory.com/docs-v2/addons/advanced-search/#select
and still cannot figure it out how to do it in a proper way.

My understanding is that each individual search bar is tied to custom post type. In a default GeoDirectory plugin version we see this post type called places but in the example above post type called “Places” was removed or replaced with 1.) Fund post type 2.) Project post type and 3.) Services post type. Then each custom post type has individual custom fields structure. Okay, till here is more or less everything clear. Then I assume that i.e. Investment location field is custom made field created inside settings tab & custom field tab marked as text field and so on and so forth – okay so far, so good.

Then I get lost and could not figure it out how search boxes are made. I assume I need to go inside custom post settings and open search tab… and then ? How can I make search box to go through keywords or funds size… and how to I replace old search bar with the new one. For example here https://wpgeodirectory.com/docs-v2/addons/advanced-search/#select
Under Shortcodes section it is written gd_search [gd_search title=”GD Search”] what does it mean ? Should each new search bar have individual shortcode, how are those search bar shortcodes made…etc.

BTW it will be really nice and beneficial for novice users if someone from GeoDirectory could make a detailed video on how to build a custom directory from scratch and put it on YT because those videos showing functions are a little bit “dry” for my taste.

Thank you !
