That's why long ago I decided that mysq fulltext search is useless - stopwords which are ignored, if too many matches are found then none are returned, almost no customization, etc. I don't know who would like to use it? I suppose mysql.com uses fulltext search in their search engine - that would explain that I hardly ever can find anything using their search box in the documentation, now I don't even bother and use google to search mysql.com.
In my sites I usually use a separate table where all data for searching are indexed and prepared in a proper form (eg. stripped tags, punctuation marks, accents on letters, etc.) and then I write code in my application that will convert the phrase to search into a series of LIKE and/or REGEXP expressions joined with AND or OR and this will give me enough room for customising how the search needs to function. Alas, I don't get the benefit of the speedy index but with a bit of caching mechanisms I can cope all right.
