Hi Omer, If you mean exact match with same number of words (Emir's), you can also add an identifier in the beginning and end of the some other field like title_exact. This can be done in your indexing script or using Pattern Replace. During query side, you can use this identifier. For example, indexing "united states" with "exactStart united states exactEnd" and querying with the same. Obviously, you can have scoring issues here so only use if you want it to debug or retrieve docs.
Just adding to the all possible ways. *Anyways, I like the Keyword method.* On Tue, 3 Dec 2019 at 03:59, Erick Erickson <erickerick...@gmail.com> wrote: > There are two different interpretations of “exact match” going on here, > don’t be confused! > > Emir’s version is “the text has to match the _entire_ input.
