Subject Re: Solr mm is field Level in case sow is false
Date Wed, 29 Nov 2017 04:40:18 GMT
HI Steve,
I can’t use the copy field because i have multiple types of field ,which uses different
type of data ,examples are
1. Normal Tokenized field (normal fields)
2. Word deliminated field 
3. synonyms field (synonyms can be applied on one or two fields not all according to our requirement)
4. Ngrams field (model related field, partial word matches)
