To ensure that the result of your search corresponds to your expectations, here are a few basic principles.

Simple search

To carry out a search, enter one or several words separated by spaces. When interpreting terms searched these spaces will be considered as "AND", which means that the companies selected will be those for which ALL the terms appear in their sheet.
The words that you are looking for are used as you have entered them, the jokers and the wildcards (*,%, ...) are not taken into consideration.

Phrase search

If you want to find a phrase, place it quotation marks. It will thus be considered as one single chain of characters and the result obtained will be a list of companies that contains these words in the same sequence. E.G. "product database".
