=== Smart Chinese Analysis Plugin
|
|
|
|
The Smart Chinese Analysis plugin integrates Lucene's Smart Chinese analysis
|
|
module into elasticsearch.
|
|
|
|
It provides an analyzer for Chinese or mixed Chinese-English text. This
|
|
analyzer uses probabilistic knowledge to find the optimal word segmentation
|
|
for Simplified Chinese text. The text is first broken into sentences, then
|
|
each sentence is segmented into words.
