Hi all, I would like to know if there is a limitation of the number of words that we can give to the keyword\_marker instruction ? And if there is a big impact on the performance of ES ?

Tokens are stored in a hash table, which provides random access in constant time so I would not worry too much about performance. However, these tokens will be stored in memory so you should keep the size of the list reasonable.

Thanks. Is a list of 10 000 words is too big ?
