How to extract multiple fields from one regex

I try to extract several fields from my log but for some reason it does not work 😞
Here is my props:

[ev_event]
EXTRACT-sourceTask,groupName,virusName,targetUser,targetUserType,infectedObject = wstrTaskDisplayName="(?P[^"]+)", wstrGroupName="(?P[^"]+)".*strEventType="GNRL_EV_VIRUS_FOUND", wstrDescription="Результат:\s+Обнаружено:\s((?P[^\n]+))\nПользователь:\s+(?P[^()]+)\s\((?P[^)]+)\)\nОбъект:\s+(?P[^"]+)

There are Russian letters, but it's ok. Regex is 100% valid, I created it via Splunk Field Extractor, but I don't see these fields in the fields list on the left and can't search its values. However, when I open 'extract new fields' again, my fields are highlighted. What did I do wrong?

Here is log example:

"2016-04-27 10:56:35" nSeverity="4", wstrTaskDisplayName="Файловый Антивирус", wstrGroupName="OFFICE", wstrProductBuildNumber="10.2.4.674", strEventType="GNRL_EV_VIRUS_FOUND", wstrDescription="Результат:     Обнаружено: EICAR-Test-File
Пользователь:     DOMAIN\TEST_USER (Инициатор)
Объект:     C:\users\test_user\desktop\11.txt", wstrPar1="NULL", wstrPar2="C:\Users\test_user\Desktop\11.txt", wstrPar3="NULL", hostName="USER-COMP", domainName="domain.ru", tmRegistrationTime="2016-04-27 10:56:35.68", nId="1944850"

Try this in your props please:

[ev_event]
EXTRACT-anExtractionName=(?ms)wstrTaskDisplayName="(?<sourceTask>.*)", wstrGroupName="(?<groupName>.*)", wstrProductBuildNumber=".*", strEventType=".*", wstrDescription="\W+(?<virusName>.*).*Пользователь:.*\\(?<targetUser>.*).\((?<targetUserType>.*)\).*Объект:\s+(?<infectedObject>.*)", wstrPar1=".*", wstrPar2=".*", wstrPar3=".*", hostName="(?<hostName>.*"), domainName="(?<domainName>.*)", tmRegistrationTime=".*", nId=".*"

Also make sure this props.conf is in the app you're using when you're doing the search, because this is a search time extraction and its scoped to the app unless you're putting it in /etc/system/local. I took the liberty of extrainign hostName and domainName as well. Hopefully you can use my example to expand upon your extraction as you wish.

this might sound stupid but did you use smart or verbose search mode and not fast mode when you where searching?
