Here's some code I used to add a folder path as a user scoped rule (there are default scope rules that include or exclude folders, and user scoped rules that override these where necessary).ĬSearchManager manager = new CSearchManager() It's pretty easy to use but the documentation is a little sparse.

Sadly, there's no support for INSERT, UPDATE or DELETE in Windows Search SQL but there is a different API to allow you to play with the indexes.Īs a managed developer, I opted to use the that some helpful folks created as part of the Microsoft Windows Search 3.x SDK. The final obstacle for your application of Windows Search might be getting the files you want into the index. There's lots more available in Windows Search SQL - you can ORDER BY and even weight individual columns differently with the RANK BY statement. UPDATE - read this post ' Windows Search and the file scheme' before copying this code! WHERE FREETEXT( 'your query') AND SCOPE = 'c:\users\josh\godeep' WHERE FREETEXT( 'your query') AND DIRECTORY = 'c:\users\josh\justhere' SCOPE - when you want to limit your search to specific folder and its sub-folders. No problem!ĭIRECTORY - when you want to limit the search to single directory. Truly awesome so far - but I wanted to limit my search to a specific directory with documents that pertain only to this application. The FREETEXT alternative is really what I was looking for and does exactly what I needed without the need to hack the query to pieces: WHERE CONTAINS( '"where" AND "are" AND "you"') So "where are you?", "windows vista" and "windows!" were all invalid.īlindly, I decided to chop these queries up using regular expressions and rebuild them so that they'd become. This was fine when the query was "powershell" or "windows" but any non-word character blew it up (including spaces). SELECT System.ItemUrl FROM SYSTEMINDEX WHERE CONTAINS( '') Initially, I opted for CONTAINS and started building queries like the example below, passing the value from a textbox the user plonks his search into: There are two key ways of doing this: CONTAINS and FREETEXT. Very cool - but I needed to search documents and dive into the guts of the text. items with a due date (includes mails and tasks remember!)

Using (OleDbConnection conn = new OleDbConnection( Here's some sample code that executes a query and populates a Windows Forms datagrid with the results: NET Developers, we just use System.Data's OleDb Providers. The way in which we query the index should be familiar to most.

I really didn't fancy that.Īnd so my attention was drawn to Windows Search.īuilt on the original Windows Desktop Search that you added to Windows XP, Windows Search is part of Vista (and Windows 7 builds on this even more) - fortunately, it has an API that we can all use. You can only get at it using lots of nasty reflection and 'going unsupported'. Regrettably, the implementation of this search is somewhat, err, encapsulated. My first port of call was to llok at how the Find feature had been implemented in WPF's DocumentViewer control: Naturally, I was keen to leverage an existing mechanism to do this. One thing I wanted to do was have an integrated search that could whizz through my repository of documents and have the results right there in my application. I've been working on a WPF app that does lots of stuff with XPS (you don't say Josh! Merging XPS Documents, Cracking an XPS in WPF). Using Windows Search in your applications
