Hi Muhammad, If the limit(s) are static, you can still do it at index time: Assuming you send “content” field, you index it fully (and store if needed), and you use copy field to copy to content_limitted field where you use limit token count filter to index only first X tokens: https://lucene.apache.org/solr/guide/6_6/filter-descriptions.html#FilterDescriptions-LimitTokenCountFilter <https://lucene.apache.org/solr/guide/6_6/filter-descriptions.html#FilterDescriptions-LimitTokenCountFilter>
You can use CloneFieldUpdateProcessorFactory in combination with TruncateFieldUpdateProcessorFactory to do the similar thing in update request processor chain.
