The following table lists additional Search Service properties that you can tune:
Parameter
Description and Recommendation
Index Location
Directory that contains the search index files.
To save index files, you allocate disk space on one of the nodes in the domain. Make sure that the disk location has enough space to write index files.
Recommendation: Disk space must be approximately twice the size of the schema.
Extraction Interval
Interval in seconds at which the Search Service updates the search index. The Search Service checks for changes in the metadata before reindexing. Default extraction interval is 60 seconds.
Recommendation: The extraction interval must be greater than or equal to the time taken to complete indexing the first time.
