Searching a application name returns "sorry no match" in Ubuntu 14.04

Question

All was working well in my Ubuntu 14.04. Suddenly I couldnt search any apps through search (by pressing super key).

I used to type "Terminal" or "System Monitor" and it would display those apps. But now, when I typed "Terminal" and any other apps like Chromium, it displays "sorry no match found". How to resolve this?

I can open System Monitor by pressing Alt + F2 and using the command gnome-system-monitor.

If you run in a terminal com.canonical.Unity.Lenses disabled-scopes what is the output? — Jacob Vlijm, Feb 21 '15 at 11:35
@JacobVlijm do you mean gsettings get com.canonical.Unity.Lenses disabled-scopes? — Jos, Feb 21 '15 at 11:46
Try this: install dconf-editor (this saves entering a lot of long commands). Open dconf-editor and open the key com.canonical.unity.lenses. On the right-hand panel, click on each of the keys and click the button "Restore defaults". This should restore your search settings. — Jos, Feb 21 '15 at 12:03
tried it. But "Set to Default" button is hidden on all the keys. — Anbu, Feb 21 '15 at 12:10
@Jos Ah, shoot, thanks, posted obviously in too much a hurry :) — Jacob Vlijm, Feb 21 '15 at 12:14

@JacobVlijm You could post this as an answer (with link provided as source) would help this out. :) — No Time, Feb 24 '15 at 01:30

Accidentally changed settings?

It could be that you accidentally changed the default search settings in Dash. I would check two things first:

run:

gsettings get com.canonical.Unity.Lenses home-lens-default-view

This should return a list, in which applications should appear, like:

['applications.scope', 'files.scope']

If not, you can set it to default by the command:

gsettings set com.canonical.Unity.Lenses home-lens-default-view "['applications.scope', 'files.scope']"

The applications Lens might be disabled for some reason, to check:

gsettings get com.canonical.Unity.Lenses disabled-scopes

It should return:

@as []

If not, reset it by:

gsettings set com.canonical.Unity.Lenses disabled-scopes "[]"

If that doesn't work

If all fails, as an alternative, you can reset the Unity configuration as described here:

You'll need Unity Tweak Tool:
```
sudo apt-get install unity-tweak-tool
```
Run the command:
```
unity-tweak-tool --reset-unity
```

@Anbu if this solved your problem (as you mentioned in a comment), would you consider accepting the answer? It creates clarity and makes sure the question does not seem unanswered. — Jacob Vlijm, Feb 24 '15 at 18:47
