> 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.
