Looking for feedback to improve user testing and usability platform

Is there any search platform which computes indexes based on semantics of words in text?

I want to store emails for my data science project and search for different phrases in my entire collection. The phrases I will be searching might be different than the actual words, but I should always get those emails in return.

What is the best platform to do this? I need a search db that computes indexes in an email based on the semantics (consider stemmers, synonyms etc), elasticsearch or cloudsearch directly won’t work.

Also, how effective is FREETEXT function in SQL Server? Can it serve the purpose?
