I like this discussion pretty much. It is a really complex topic.
I want to add another example. In english, you are saying "it is a red dress". In german it would mean "es ist ein rotes Kleid" (words can be translated in the same order). However the basic form of "rotes" is "rot". If your users are searching for "rotes Kleid" they may also expect matching documents like "Kleid rot" or something like that. To draw a conclusion on the discussion until now, I want to quote Mark: Mark Miller-3 wrote: > > are you going to > want documents that had run and water when you searched for running > water? In most cases, everyone disagrees. Let's have an abstract view at this topic: When should an application stem a word, and when not? In my opinion, it allways makes sense to stem adjectives - and in most languages one can decide whether a word is an adjective or not, even if it is not known by any dictionary. But what about verbs? Is a stemmed verb less worth than an stemmed adjective? In cases of titles - which are short - I think yes. In cases of longer types of texts like articles and descriptions - I am not sure. The same applies on lemmatization. Yes, reducing the word will work fine in a lot of cases, where the word is known. However, does it really makes sense all the time? I want to emphasize that this discussion only makes sense, if we want do talk about search-applications which are tolerant and made for highly relevant search results without exact matching.
