solr与IKAnalyzer
1. solr4.10.3 must cooperate with IKAnalyzer2012FF_u1, otherwise the latter cannot be used, and an error java.lang.AbstractMethodError will be reported
2.solr5.2.1 can work with IKAnalyzer2012_V5
In addition, if you use solrj, the version of solrj and solr should be the same. And the matching httpcore and httpclient should be well matched, for example, solrj4.10.3 is matched with httpcore4.3, and httpclient is 4.3.1, otherwise some inexplicable errors will be returned. (SolrServer outdated etc.)
