Try the following:
- create a new empty writer-document
- place a text:  text text text text 
- run the following Basic code:

oDesc = ThisComponent.createReplaceDescriptor()
oDesc.SearchString = "text"  ' find for string "text"
oFoundAll = ThisComponent.findAll(oDesc)   ' find all occurences 
msgbox oFoundAll.count   ' get 4 occurences 
ThisComponent.getCurrentController.select(oFoundAll())  ' select all occurences 
' You'll see there's only 3 occurences of collection oFoundAll is selected,
' the cursor is placed on end of first occurence of "text" string, without highlight

This behaviour has several unnatural consequenses:
1. the clipboard/transferable-content will not be the same if one tries to work
with it after performing a selection
2. more complicated and causing uncertainty in the mass processing of selected texts

This issue occurs with OOo 3.4.1., with OOo 3.2.0 works good.
