MoreLikeThis & Synonyms
Hi
It turns out that MoreLikeThis handler does not use queryTime synonyms
expansion.
It is only compatible with indexTime synonyms.
However multiword synonyms are only compatible with queryTime synonyms
expansion.
For this reason this does not allow the use of multiword synonyms within
together with the MoreLikeThis handler.
Is there any reason for the MoreLikeThis feature not compatible with
Multiword Synonyms ?
Thanks

From this blogpost [1] I deduced multi-word synonyms are only compatible
with query time expansion.

From my tests, MLT does not expand the query with synonyms. So it is not
possible to use query time synonyms nor mutli-word. Only index time is
possible with the limitations it has [1]

I am running solr 7.6.

bq. However multiword synonyms are only compatible with queryTime synonyms
expansion.
Why do you say this? What version of Solr? Query-time mult-word
synonyms were _added_, but
AFAIK the capability of multi-word synonyms was not taken away. Or are
you saying that
MLT doesn't play nice at all with multi-word synonyms?
What version of Solr are you using?
Best,
Erick
