Fix bug with a repeated search query

[DmytroAlipov]

Description

An issue has been found with research if no changes are made to the search field:

• first search:
  

• second search:
  

This fix allows actions to be ignored if the current search query matches a previous query.
If there are any changes in the search query, then it is sent to the backend.
