Hi Derek,
Why does aggressive stemming worries you? You might have false
positives, but that is desired behavior in most cases. In your case
"iphone" documents will also be returned for "iphon" query. Is this
something that is not desired behavior? You can have more than one field
if you want to prefer matches with exact wording, but that is
unnecessary overhead in most cases.
Regards,
Emir

Hi
I am using EnglishMinimalStemFilterFactory to reducewords in plural
forms to singular forms.
The filter factory is not reducingthe plural formof 'es' to the
singular form correctly. It is reducing correctly for plural form of 's'.
"boxes" is reduced to "boxe" instead of "box"
"glasses" to "glasse" instead of "glass" etc.
I tried with PorterStemFilterFactory, itis able to reduce the plural
'es' formto singular form correctly. However itreduced "iphones" to
"iphon" instead.
Is there other filter factory that can reduce pluralto singular
correctly?
