示例1: addSearchTermQueries
import org.apache.lucene.search.PrefixQuery; //导入方法依赖的package包/类
/**
* Adds for every field in {@link IIndexTypeConf} a {@link TermQuery}, {@link PrefixQuery} and
* a {@link FuzzyQuery} with a suitable boost relative to the given base boost.
*
* @param indexType the type in which should be searched.
* @param search the search text.
* @param subQuery the {@link BooleanQuery} to add the sub queries.
* @param baseBoost highest possible boost of the query. The more the match is exact
* than a bigger boost will be used.
