Berkeley DB page size (see Berkeley DB documentation)
Berkeley DB cache size (see Berkeley DB documentation) Cache makes a huge difference in performance. It must be at least 2% of the expected total data size. Note that if compression is activated the data size is eight times larger than the actual file size. In this case the cache must be scaled to 2% of the data size, not 2% of the file size. See Cache tuning in the mifluz guide for more hints. See WordList(3) for the rationale behind cache file handling.
Maximum size of the cumulated cache files generated when doing bulk insertion with the BatchStart() function. When this limit is reached, the cache files are all merged into the inverted index. The value 0 means infinite size allowed. See WordList(3) for the rationale behind cache file handling.
If true all Insert calls are cached in memory. When the WordList object is closed or a different access method is called the cached entries are flushed in the inverted index.
Activate compression of the index. The resulting index is eight times smaller than the uncompressed index.
