Subject: First ICU chain integration in relevance ranking of pazpar2.
X-Git-Tag: PAZPAR2.1.0.0~106
X-Git-Url: http://jsfdemo.indexdata.com/cgi-bin?a=commitdiff_plain;h=39b063c2816d8d221a0af5b6852af78035df7e4a;p=pazpar2-moved-to-github.git

First ICU chain integration in relevance ranking of pazpar2.
Tokenization not working correctly, need more debugging.
