When editing an object who has an attribute of type "Object relation" or "Object relation browse" and adding an object you where redirected to module content/browse where you can select all objects to add.
In this view the search shows as result not all objects that match to the search.
When you try to search the same word in normal backend (not content/browse ) the search shows more results than before.
Why ?
Additional try to seach in a special location while in content/browse. The result is sometimes different between seaching in a special location and location all regarding the resulted classes.

I can not find any logic for this behaviour.

Steps to reproduce

-Use standard ezPublish 4.0.3
1) -Go into backend and search for "Lyon" in all content : result count will be 20 (of class article, gallery, image, Blog post and frontpage)
-Edit an object of class "frontpage" for example.
-Add an object at attribute "Billboard"

• Search for "Lyon" in all content : result count will be 10 (of class frontpage nd article)

2) -Edit an object of class "frontpage"
-Add an object at attribute "Billboard"

• Goto MediaLibary and search for "Lyon" in current Location : result count will be 1 (of class image but there exists also banners with with Lyon)
• Goto MediaLibary and search for "Lyon" in all Location : result count will be 10 (of class article and frontpage)
