StandardAnalyzer should work fine, mark the field as indexed, no need to store it unless you want to retrieve it for display.
Query via QueryParser using "tagname: updateC*" or programatically via PrefixQuery. Although I'm not sure exactly what you mean by "strict prefix". If you mean that the prefix should match exactly on case, punctuation etc. maybe use KeywordAnalyzer instead. -- Ian.
