subtree_hits_cache

subtree_hits_cache

Max common subtree hit cache size, per-query. Optional, default is 0 (disabled).

Limits RAM usage of a common subtree optimizer (see the section called “Multi-queries”). At most this much RAM will be spent to cache keyword occurrences (hits) per each query. Setting the limit to 0 disables the optimizer.

Example:

subtree_hits_cache = 16M
