Hi Jamal, I assume you are using the Synonym token filter. >From the observation I can assume you are using it only at indexing time. This means that when you index you are :
1) given a row in the synonym.txt you index all the terms per row in place of any of the term in the row . 2) given any of the term in the left side of the expression, you index the term in the right side of the expression You can verify this easily with the analysis tool in the Solr UI .

Please take a look to the analysis tool as well to understand better how the offsets are assigned. I remember long time ago there was a discussion about it and a bug or similar raised.
