Subject [jira] Commented: (LUCENENET-151) Bug in Lucene.Net.Search.MultiPhraseQuery.ExtractTerms(System.Collections.Hashtable terms)
Date Fri, 19 Sep 2008 09:48:44 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12632604#action_12632604

Iliev Andrei commented on LUCENENET-151:
----------------------------------------

I don't  like the approach to replace .Add by using Item property: myCollection.Add(Key,myValue)
 -> myCollection[Key] = myValue. The reason:  java version of .Add adds an item only if
the key does not already exists. But myCollection[Key] = myValue will replace old value with
a new one. Though it is looked as not essential  there are cases where it might be important.
In  such a case it would be very hard to find  the problem. So my point: .Net version should
be close to the java version (mimic java-object ) as much as possible. I agree with Digi 
it would be better to write a new java compatible Set/Hashtable interface.

> when a query contains duplicate terms, attempting to add them to the Hashtable argument
results in a thrown System.ArgumentException containing the message: "Item has already been
added."
