regular expression in find-tag-regexp

Hello,
     I notice that the same regular _expression_ will give different matching result in find-tag-regexp (C-M-.) and in isearch-forward-regexp (C-M-S). \
I have the following tags
MatGetArray_SeqAIJ
MatGetArray(....)
MatGetArray_SeqBAIJ()
MatGetArray_MPIDense()
MatGetArray_SeqDense()
MatGetArray_SeqSBAIJ()
matgetarray_()

If I use the Mat.*GetArray.* to search, find-tag-regexp will only match MatGetArray_SeqAIJ but isearch-forward-regexp will match all except the lower case matgetarray(). If I use the MatGetArray, find-tag-regexp will match all of them including the matgetarray()? Anyone can explain why it is so? If I want find-tag-regexp to find all of them( with or without the matgetarray()), what regexp should I use? Thank you.

Shiyuan
