I want to provide variations of field "title" as its synonyms. I expect that if a user searches for the exact title or any of its variations, this particular document should be returned as first.

eg. I have many faq documents. one of those is

below is the required faq with its synonymous questions

I read about complexities that arise in case of multi word synonyms. Can anybody suggest how can I map all those question variations as equivalent to the actual question and referring to the same document.

One of the solutions that I though of as adding all ques variations as another property field in my index and while querrying using query more\_like\_this providing title(here it refers to actual title of question faq) and ques variations list.

below is my code for indexing, ingested data and querying  
PUT faq  
{  
"mappings": {  
"articles": {  
"properties": {  
"title": {  
"type": "string"  
},  
"ques\_var": {  
"type": "string"  
},  
"detail": {  
"type": "string"  
},  
"detail\_html": {  
"type": "string"  
},  
"account\_id": {  
"type": "long"  
}  
}  
}  
}  
}

Here my "title" would be "How to log in into facebook?"  
my "ques\_var" would be ["facebook login?", "where to login for facebook", "do i need to sign up for logging into facebook"]

and my query is like this below:

eq.query(Query.more\_like\_this([constants.TITLE, constants.QUES\_VAR], input\_data[  
constants.QUERY],  
min\_term\_freq=options.faq\_min\_term\_freq,  
min\_doc\_freq=options.faq\_min\_doc\_freq))

kindly suggest me if this approach is right
