B Jayachithra 1

Tried below query to search subject contains attach ,but filter is not applied correctly and all messages are listed

sub="attach";
LinkedList<Option> requestOptions = new LinkedList<Option>();
requestOptions.add(new HeaderOption("ConsistencyLevel", "eventual"));
requestOptions.add(new QueryOption("$filter=subject eq", sub));

	MessageCollectionPage messages = _appClient.users(user).mailFolders(folder).messages()  
	    .buildRequest()  
	    .top(1000)  
	    .count(true)  
	    .get();

Hi @B Jayachithra ,

Please find below sample snippet using Java for Microsoft Graph with GET /me/messages?$filter=subject eq 'test'.

LinkedList<Option> requestOptions = new LinkedList<Option>(); requestOptions.add(new HeaderOption("Prefer", "outlook.body-content-type=\"text\"")); MessageCollectionPage messages = graphClient.me().messages() .buildRequest( requestOptions ) .filter("subject eq 'test'") .get();

Hope this helps.

Hi,I am trying to pass 'test' as string variable and use variable in filter/search options.
For eg .

String sub='test';

LinkedList<Option> requestOptions = new LinkedList<Option>();
requestOptions.add(new HeaderOption("Prefer", "outlook.body-content-type=\"text\""));

MessageCollectionPage messages = graphClient.me().messages()
.buildRequest( requestOptions )
.filter("subject eq <sub>")
.get();

If I run above code,it fails with "Exception in thread "main" com.microsoft.graph.http.GraphServiceException: Error code: RequestBroker--ParseUri
Error message: Could not find a property named 'sub' on type 'microsoft.graph.message'.
"

How to pass string to be searched to variable and use in search/filter options.I am using clientcredential flow and need to search on below properties of message
Subject,
From
Fromdate

Hello @B Jayachithra ,

Have considered using string concat?

MessageCollectionPage messages = graphClient.me().messages() .buildRequest( requestOptions ) .filter("subject eq <sub>") .get();

You can achieve with something like this.

string strSearchValue="some test"; string strSearchFilter="subject eq '" + strSearchValue + "'"; MessageCollectionPage messages = graphClient.me().messages() .buildRequest( requestOptions ) .filter(strSearchFilter) .get();

Hope this helps.
