Timothy Potter commented on SOLR-6878:
--------------------------------------
bq. why not let the new "expand" feature just be syntactic sugar on adding
symetric sets of KEY=>VALUE mappings via lists of lists?
Good idea! I'll start down that path as it seems pretty straight-forward to
implement w/o all the state management issues as you mentioned. Thanks Hoss.

> 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.
