# BestTermHash

Set `BestTermHash` to `False` to turn off the best term hash structure. This option can reduce the IDOL Server memory usage and increase indexing speed, at the expense of increasing the disk I/O when best term information is required (for example, during QuerySummary operations or Suggest actions).

In general, Micro Focus recommends turning off `BestTermHash` only if you are regularly indexing a very large number of new terms.
