hi...
i want to filter a filtered QSortFilterProxyModel..
for example items such this :
proxyModel items =
"123a"
"1234a"
"12345"
"1234567"
"12345678a"
....
result proxyModel->setFilterRegExp(regExp("12345")) =
"12345"
"1234567"
"12345678a"
now i want to filter just tree above item with proxyModel->setFilterRegExp(regExp("a"))
i want the result just be "12345678a" no "1234a" and "12345678a"

So what are you asking for? The correct QRegExp to use? How to chain together multiple QSortFilterProxyModels? What?

i want to have advansed search like google search.. and , or , unwanted word..
for and i use this \bword1\b.+\bword2\b
it just find :
word1 some word2
and not find :
word2 some word1
whereas i want to find both..

Then you need to have a QRegExp that contains the logical OR of both forms of your search phrase:
(word1 some word2) | (word2 some word1)

this way is good for just tow word :
the code must be :
(\bword1\b.+\bword2\b|\bword2\b.+\bword1\b)
so for tree word :
(\bword1\b.+\bword2\b.+\bword3\b|\bword1\b.+\bword 3\b.+\bword2\b|\bword2\b.+\bword3\b.+\bword1\b|\bw ord2\b.+\bword1\b.+\bword3\b|\bword3\b.+\bword2\b. +\bword1\b|\bword3\b.+\bword1\b.+\bword2\b)
i think this way for tree or more word is not good..
