Plugin cannot handle hyphens and long words

Does it work if you turn on BOOLEAN mode in the Plugin settings page?

The setting active will disable the contextual search feature and instead go for a simple word search feature which is weighted by how many terms are actually found.

The contextual (fulltext) feature doesn’t work in these cases as per the mySQL manual:

Some words are ignored in full-text searches:

Any word that is too short is ignored. The default minimum length of words that are found by full-text searches is four characters.

Words in the stopword list are ignored. A stopword is a word such as “the” or “some” that is so common that it is considered to have zero semantic value. There is a built-in stopword list, but it can be overwritten by a user-defined list.

The search result is empty because the word “MySQL” is present in at least 50% of the rows. As such, it is effectively treated as a stopword. For large data sets, this is the most desirable behavior: A natural language query should not return every second row from a 1GB table. For small data sets, it may be less desirable.

Your welcome.
