By adding symbols_to_index to all the fields [around 10 fields] , will it increase the memory usage to a greater extent , there will be around 300K documents ,

Hi Chandar, Enabling

symbols_to_index

causes Typesense to preserve and index additional characters as part of the in-memory search index. This might increase the number of distinct tokens, depending on how many distinct special characters you have between the same set of tokens (word). Since Typesense is an in-memory database, the more distinct tokens you have, the more memory is needed. I would recommend you to benchmark it with your dataset to assess the exact memory impact
