Subject Re: Problem when i'm trying to search something

Hey Anon15

It sounds like your encountering a heuristic known as stemming. Stemming
takes various of words and reduces them to a base form. For example


might all get reduced to "jump"

So now when a user searches for "jump" they can retrieve all docs with the
various forms of the word "jump".

There's various algorithms that Solr/Lucene use for stemming. They all
represent hueristics that work well for most cases. Some stemmers are very
aggressive in how they reduce to a common form, others are less aggressive.
You can read more about Solr/Lucene's stemmers here:

All of these are configured in your Solr schema in the corresponding field
type's analysis chain. Do you know what field type is being used for this
field you are searching? Would you be interested in sharing, and we could
give you even more info?
