When performing a search on name or address with "Loose Search" on, the system will break your searching string into parts and return names or addresses in which each part of the search string can be found.
When performing a search on name or address with "Strict Search" on, the system will return names or addresses in which the whole search string can be found.
For example, given the following company names:
- Girl Toy Limited
- Boy Toy Limited
- Boy Toy And Tool Limited
If the search string is "Toy Limited", with "Loose Search" on, all the above names will be returned.
However, when "Strict Search" is on, only the first two names will be returned.
The benefit of "Loose Search" is that as long as you remember parts of your target without knowing the positions of the parts, you still can find your target.
But the downside is it gives you a larger result set. Say if the search string becomes "Limited Toy", "Loose Search" will still return the above three names.
On the other hand, the "Strict Search" option gives you a smaller result set but requires that you know exactly what you are searching.
Say if the search string is now "Toy And Tool", "Strict Search" will only return "Boy Toy And Tool Limited".
Bear in mind that both search types are case insensitive. So "Toy And Tool" and "TOY AND TOOL" will give you the same result.
