Why is the "-" symbol a problem?

When you search in the ASK search bar, if you put "-" in your search query, the article you are looking for may not be found.

Why is that so?

ASK's search bar behaves similarly to other search engines. And “-” is the symbol most search engines use to exclude certain words. Therefore, if you search by adding the "-" symbol, the results will exclude articles containing that word.

Example of the most unfortunate case

If you search by adding a "-" sign to a single word as shown below, no articles will be found.

Unfortunately, some of AhnLab's products have error codes that start with a "-" symbol. If you want to search for these error codes, please search without the "-" symbol.

Is there an example of a correct search with "-"?

If you want to search without certain words, the "-" symbol works great for this.

If you want to search for “installation” as shown below, but want to exclude the word “V3” from the search results, you can enter it as follows.
