The operation has timed out

[Toniyo_Jackson]

Getting The operation has timed out error when trying to execute the below code. 

DocumentQuery docQuery = app.Core.CreateDocumentQuery();
docQuery.AddTextSearchConstraint(DocumentQuery.TextSearchType.IDOLFullTextSearch, "Fee");

KeywordType accountKeywordType = app.Core.KeywordTypes.Find("Account Number");
docQuery.AddDisplayColumn(accountKeywordType);

// adding by generic DisplayColumn type
docQuery.AddDisplayColumn(DisplayColumnType.DocumentDate);

long maxDocuments = 10;

DocumentList docList = docQuery.Execute(maxDocuments); - Getting error here

Please tell me how to solve this issue?

From what I see you are searching every document type in the system with a full text search looking for the word "Fee".  You are probably simply searching too many documents for the result to come back in a timely manner.  I would suggest either using specific document types or a custom query along with a date range to limit your search.
