### What problem does this PR solve?

For CJK based analyzer, AhoCoasick is directly used.
For stemmer based analyzer, call analyzer again. 
The StandardAnalyzer is modified to support char offset, the highlighter
will call such analyzer again to output precise offset.
If all analyzers could output char offset, then these information could
be stored within inverted index, then we could continue improve the
highlighter at that time.
