The 3.8.1 release brings a number of minor features
and fixes several issues.
STC algorithm improvements.
The STC clustering has been improved. It now supports stemming algorithms
and picks the representative phrase from a set of stem-equivalent versions.
The algroithm now respects stop labels dictionary.
Webapp's query word highlighter is now configurable/ replaceable.
The default highlighter that comes with the webapp now has more
tuning options (custom sanitizing regexp pattern, custom pattern
for ignoring certain expressions).
Workbench supports overrides of components and attributes.
This can be used to customize and tweak initial attributes
of document sources and algorithms.
Minor bugs squashed.
There was an issue with proper ordering of multi-lingual clusters
when FLATTEN_ALL option was selected. The webapp did not support
non-numeric document identifiers.
