Hi, We considering using synonyms filter at index time and would like to understand the effect of updating the info of the file. The action I perform to reload the synonyms files are: 1. replace the file 2. close and open the index I do see the new file data is reloading by verifying with analyze api some of the newly added synonyms. What I would be happy to clarify if re-index is required of already indexed data (prior to the files changes). Currently when querying this data I am not able to match it as expected by the new synonyms.
