Synonym map for similar terms

Copper Contributor

Will adding a synonym map for similar terms, boost the search score of the search term that was present inside a synonym map since all the synonyms get matched?

Hey there - I saw this post got posted twice, so I've moved the additional content to this post and removed the duplicate. Just wanted to let you know.

@Roshini Yes - if the synonym map causes there to be extra terms to match the query, this will cause the document to be boosted higher. The biggest thing synonym maps are going to do for you is improve the recall of the query. All matching terms will be pulled and then fed into the BM25 algorithm
