Lucene removing some words while searching

[M å n i s h]

 

Hi erik and other gurus,

 

I have some doubts over double quote queries (as it is)

Suppose I search “lucene user forum” it should give correct continuous
occurrence of full text , 

 

But if I search for “when they occur” lucene is searching for “when occur”
also.

I think lucene is treating “they”  as stopword and removing it from the
search string.

But If I use double quotes it should not happen.

 

Thanks in advance,
