Looks like PorterStemFilter converts "Lowe's" to low. Not very surprising.
Options include . Drop the stemming . Index stemmed and non-stemmed variants and search both, maybe boosting the non-stemmed variant. If you really want exact matches only, you may also/instead want untokenized fields. Apostrophes etc can be a problem. Look into what analyzers do and use Luke to see what is indexed. -- Ian.
