Learn the AND, OR, NOT, and keyword search logic

Learn the logic behind Vainu's search functionalities.

You may have noticed that simply by clicking on the filter you have selected, you can change its colour to red, blue, or green. The colours represent different search conditions – OR being the default state.

OR searches

You can recognize OR search from its blue colour. 

OR search is the basic search.  If you look at the filters selected on the picture below, the search would find me companies that either use Giosg OR Zendesk OR Userlike Chat. So the company needs to have any one of the three technologies, but not all of them.

AND and ALL searches

You can recognize AND search from its green colour.

AND search is the second most common search option in Vainu. Any filters you give in your search will ALL need to match for the company to show up in your search. 

If you look at the picture below, it would mean that the companies need to have a revenue of over 900 000 euros AND the companies need to have 8 or over 8 employees. If both filters apply to a company, it will appear in your search results.

"I want to find companies that have Giosg OR Userlike on their website AND Zendesk."

The green colour tells you if the filter is using the AND search option.

NOT – the negative search

You can recognize the NOT search from its red colour.  

By using the NOT search, you can for example remove companies that are in a static list from your search results, like in the picture below. That means that any company that is on the Domain import  -list would not be shown in your search results.

You can also search companies without specific website technology.

"I want to find companies that DON’T have a website on their company profile."
