Please contact Veritas Support in order to increase the number of tokens indexed by eDiscovery. Please note that increasing this property has implications on the indexer component.  If the property is increased, a user may encounter memory-related issues when processing documents which push the limit. Extra care should be taken while increasing the property and should be increased by small incremental amounts.

eDiscovery will parse a document item into “tokens” (generally, words) for indexing. By default, eDiscovery does not index the item past the first 1,000,000 tokens (note that emails and their attachments are considered separate items and the system will index the first 1,000,000 token for each item). The indexing token limit can be adjusted based on a tunable property.
