2. A new project dialog will appears. Type the file extensions that you want to index.

Advanced Usage

For symbol queries, advanced options can be entered: There is no spacing in between e.g. /a10, /n3, /xinclude

• /a NumberOfLinesAfter
• /b NumberOfLinesBefore
• /n NumberOfLinesBeforeAndAFter
• /f FileNameToMatch
• /x PatternToExclude

In addition, regular expression can be entered for the queries: e.g. .*mainWindows, (_clicked|_Pressed) It will match all ("and" condition) if multiple symbols are entered for queries.

Tips

Display result lines before and after

In the text field for symbol, "/n3" could be used to display 3 lines before and after

Match for multiple symbol

Multiple symbols (and condition) could be input for symbol queries. e.g. Multiple match are input "CMainWindow", "_on" as queries.

Show multiple project

Regular expression could be used to filter the project name and source filename name. e.g. "Or" condition for project name using the pipe "|" regular expression.
