Double Bracket Search

Posted by David_Crandall, Last update over 5 years ago


This action is an advanced search function meant to mimic the double bracket searching found in applications like nvALT and Bear. Note however, it overrides the double bracket search if any text is selected and prompts for a search term if no other conditions are found.

Search Order

The search order is as follows:

  1. If a selection is made, search for that
  2. If no selection is made but one double bracket exists, search for that
  3. If multiple double brackets exist, prompt for which one to search
  4. Else, prompt for a search term


I recommend mapping this action to a hot key combo like command+alt+F. It makes it easier to use quickly. At least, that’s what I’ve done.

    	//p.isCancellable = false;  <-- Kill this too;
    	var queryTerm = p.fieldValues["searchTerms"];
    // 4. Should never reach this point BUT lets you know if a scenario was missed
    else {
    	alert("Something went wrong. :(");
    	var queryTerm = "";
    let queryString = queryTerm;
    // Create temporary search workspace
    let ws = Workspace.create(); = workspaceName;
    ws.tagFilter = tagFilter;
    ws.queryString = queryString;
    ws.setInboxSort("created", true);
    ws.showPreview = false;
    ws.showLastAction = false;
