Examples of org.apache.maven.index.expr.UserInputSearchExpression

org.apache.maven.index.expr.UserInputSearchExpression
UserInputSearchExpression is a search expression usually coming from user input (like some UI dialogue, UI element or CLI). It will be normalized and tokenized and then a search will happen against it. Search expressions of this type will always provide "broader" (scored, not exact) results, since it defaults to prefix searches and assumes "non complete" input. @author cstamas
