# BestTermMemoryMaxSize

The maximum amount of memory (in kilobytes) used by the Best Term cache.

IDOL Server stores information on terms in a structure in memory, to provide fast generation of best term fields for documents at index time, and to aid in the population of the unstemmed term cache for Wildcard matching and spelling correction.

If the number of distinct terms in a server is unusually large, the requirements on memory of this structure might be large. In these situations, you can limit the maximum amount of memory used by the cache by setting the `BestTermMemoryMaxSize` parameter.
