@ChristianGerloff When you say remove last added chars of string, do you mean remove the last query string?

Example:

If a query string is: [hyperscanning] AND [fNIRS], then when the user clicks the button, fNIRS should be deleted and the final query string should be [hyperscanning]?

[ChristianGerloff]

Hey @kashyapm94, yes, exactly! thanks for clarifying that 😃

[kashyapm94]

@ChristianGerloff Assume that the user chose to insert plain search string directly,e.g. [brain-to-brain] AND [hyperscanning], and then want to delete it. In this case, we have a button that clears the entire string.

Should we also add the option to remove the last added chars of string for this case as mentioned in the comment above or is it only when the user builds the query string instead of entering it manually?

discuss: remove search class

For this task, it makes sense to delete the search module since we no longer need it. What do you think?
