Description

 

While using Synonym Graph Filter,  if the query string contains a multi-word synonym, it considers that multi-word synonym as a single term and does not tokenize it further.

 

For example- soap powder is a search query which is also a multi-word synonym in the synonym file as-

s(104254535,1,'soap powder',n,1,1).
s(104254535,2,'built-soap powder',n,1,0).
s(104254535,3,'washing powder',n,1,0).

 
There are 2 documents having soap(2) and powder(1) altogether.
doc1: "Sunny Berlin breast tumors soap powder"
doc2: "She is in soap Berlin today"
 
 
Scenario 1 (screenshot attached) 
 without Synonym Graph Filter => 2 docs returned  , as it checks for "soap"  and "powder" separately.
 
Scenario 2 (screenshot attached) 
with Synonym Graph Filter => only 1 doc returned, but 2 were expected. Here only "soap powder" is being checked and it is not tokenized into "soap" and "powder" and searched further.

Is it possible to expand query string - soap powder as:

Synonym(soap powder) + Synonym(soap) + Synonym(powder)

 

Thank You.
