Advanced search with multiple condition returns an unexpected result

Doing an advanced search with multiple conditions, selecting "Match all of the following" and using a Subject condition "does not contain" the result that is obtained is unexpected.

Steps to reproduce:

• open the advanced search window
• select the Inbox folder and "Match all of the following"
• add two conditions (see Image_1)
• run the search

Expected behaviour:

• the result shows only the emails that match the search conditions set

Actual behaviour:

• the result shows emails that do not correspond to the conditions set (see Image_2)
