I am currently trying to develop a basic fulltext search for my website, and I noticed that certain words like \"regarding\" are listed as stopwords for MySQL fulltext searc
The stop words are just common words in the English language. In most cases, your search results will be more relevant -- and your indices will be smaller and faster -- if you don't index these words.
You can edit the stop word list using the ft_stopword_file variable (or set it to '' to index all words as long or longer than ft_min_word_len) if that suits your needs better. You can also change the minimum indexed word length using the ft_min_word_len variable, which exists for the same reason.
