Extraction parameters
The parameters in the <Extraction> element
calibrate the size of the document batches that TEXTML Server indexes.
Starting at the oldest unindexed document, TEXTML Server takes a batch of
documents, parses them, and writes all the values to the different indexes in parallel
(according to the IndexationThreadCount value).
Extraction parameters should not be changed unless IXIASOFT Customer Support expressly recommends it.
