Email Alerts are not received...

In one of application, Email alerts are sent using SQL sp_send_dbmail stored procedure. Email alerts were working properly, but suddenly noticed email alerts are not received.

To troubleshoot the issue, first I checked the msdb.dbo.sysmail_event_log table using the below query.

SELECT log_id, event_type, log_date, description, process_id, mailitem_id, account_id, last_mod_date, last_mod_user
log_date DESC

If there is any error, you should see records with the event_type value as error.
In my case there are records with event_type value as error, and the description value for those records is same as below

The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 3 (2018-02-01T10:41:27). Exception Message: Cannot send mails to mail server. (The SMTP server requires a secure connection or the client was not authenticated. The server response was: Authentication required).  )

As per the error descript…

Scoring and Ranking in Lucene.Net

Scoring feature is used to prioritize and sort the search results by considering their relevance to the search query. For the scoring formula several facts are used. Below the formula which is used to calculate the score value is shown.
Score for term t in document d = ∑ tf (t in d).idf(t).boost(t.field in d).lengthNorm(t.field in d)Below table is listed how those functions are calculated and the description of those functions.
FunctionDescriptiontf (t in d) = sqrt(freq)Term frequency factor for the term (t) in the document (d).
This factor result to have high score value for a document
where more frequent a term occurred.idf(t) = log(numDocs/(docFreq+1)) + 1Inverse document frequency of the term.
Common terms are less important than uncommon ones.
This factor gives high value to a term which occurs only in few
documents and low value to a term which occurs in most
documentsboost(t.field in d)Field boost, as set during indexing. Boosting is used to give high priority for a term or …

Did You Mean Feature for a Search Application

This article describes how the suggesting word feature is used for a Searching application which uses Lucene.Net for indexing and searching.
Suggesting word feature is mainly useful when a user input some misspelled words and to suggest the correct word to the user.

To implement the Did You Mean feature by suggesting words, n-gram method is used. n-gram method divides the given misspelled word into sub words by considering the length of the word.
The idea behind with the n-gram method for suggesting word feature is that the misspelling occurs due to mainly one or two letters. Therefore it will only affects few n-grams. Therefore we can recognize the correct word by taking the word which share high proportion of n-grams with the misspelled word.

n-grams are created considering the length of the word.
If the word length greater than five, two grams are created having the length of three and four.
If the word length is five, then the length of the grams are two and three.
If the word length is…

Unable to edit my information using “My Settings” link in the SharePoint Site

We can find two links at the top of the SharePoint site as "My Settings" and "My Site". But I was unable to edit my information using "My Settings" link. Also when I clicked on "My Site" link it displayed an error message saying that cannot create a site because site is already created. Other users also had those two problems

I was able to solve those two problems by changing the "My Site Settings" from SharePoint 3.0 Central Administration. User Name in "My Site Settings" was changed to the Domain Users as shown in the below figure.

By changing User Name to Domain Users, it allows every user in the domain to create and maintain for him or her and maintaining his or her own profile. My Site Settings is appearing in the created Shared Service page
