Searching two string at a time in the Object of emails - luigisic - 01-07-2022

Hello,
with SearchMailBox is possible to search emails with some criteria.

I need to search emails that Object contains the string "ACC: " and emails that Object contains the string "CON: ".

Can i search both strings at a time?

This code

Code:
  SearchInfo.Date := 0;

  SearchInfo.Size := 0;

  SearchInfo.SearchKey := skUnseen;

  SearchInfo.Text := '';

  SearchInfoArray[0] := SearchInfo;

  SearchInfo.SearchKey := skSubject;

  SearchInfo.Text := 'ACC: ';

  SearchInfoArray[1] := SearchInfo;

  SearchInfo.SearchKey := skSubject;

  SearchInfo.Text := 'CON: ';

  SearchInfoArray[2] := SearchInfo;

  if IMAP.SearchMailBox(SearchInfoArray) then

is right?

It seems not right because I dont find the emails.
if i search only one string at a time i found the emails.

Where I'm wrong?

Thanks

When you specify multiple criteria to the IMAP SEARCH command, it returns the intersection (AND) of all matching criteria. Per RFC 3501 Section 6.4.4:

Quote:When multiple keys are specified, the result is the intersection (AND function) of all the messages that match those keys. For example, the criteria DELETED FROM "SMITH" SINCE 1-Feb-1994 refers to all deleted messages from Smith that were placed in the mailbox since February 1, 1994. A search key can also be a parenthesized list of one or more search keys (e.g., for use with the OR and NOT keys).

So, in your example, you are searching for emails that:

are marked as Unseen
AND whose subject contains 'ACC: '
AND whose subject contains 'CON: '

Which I suspect is probably not what you want. You probably want something more like this instead:

are marked as Unseen
AND whose subject contains EITHER 'ACC: ' OR 'CON: '

The SEARCH command has an OR <search-key1> <search-key2> search-key for that very purpose, so try this:

Code:
SetLength(SearchInfoArray, 4);

SearchInfo.Date := 0;

SearchInfo.Size := 0;

SearchInfo.Text := '';

SearchInfo.SearchKey := skUnseen;

SearchInfoArray[0] := SearchInfo;

SearchInfo.SearchKey := skOr;

SearchInfoArray[1] := SearchInfo;

SearchInfo.SearchKey := skSubject;

SearchInfo.Text := 'ACC: ';

SearchInfoArray[2] := SearchInfo;

SearchInfo.SearchKey := skSubject;

SearchInfo.Text := 'CON: ';

SearchInfoArray[3] := SearchInfo;

if IMAP.SearchMailBox(SearchInfoArray) then

This code work as I want.

You are an irreplaceable resource Smile
