Description

Hi,

After switching from SynonymFilterFactory to ManagedSynonymFilterFactory I have found out that there is no way to set an all-to-all synonyms relation. Basically (judgind from google search) there is a need for "expand" functionality switch (known from SynonymFilterFactory) which will treat all synonyms with its keyword as equal.

For example: if we define a "car":["wagen","ride"] relation it would translate a query that includes one of the synonyms or keyword to "car or wagen or ride" independently of which word was used from those three.
