Singular and plural forms, as well as inflected words are counted together. If the word "party" is one of the suggested must-have keywords, also "parties" is counted when used. Compound words will only be counted if all words have actually been used in the correct order. For "Windows 10", the single use of "Windows" does not count.
Basically, singular and plural forms, as well as inflected words are counted together. If the word "party" is one of the suggested must-have keywords, both "parties"
There are also compound words in the suggested keywords. This can sometimes lead to confusion. For example, if the keyword "Windows" is suggested and also the keyword "Windows System", the use of "Windows System" in the text, also counts only under the suggestion "Windows System". In the term "Windows" this usage is not counted. On the other hand, the use of "Windows" is not counted under "Windows System".
Compound words are counted only if all words were actually used in the correct order. This means that if the word "System Windows" appears in the text, it would not be counted under "Windows System".
