    Exception Detail:

    Hi Tam

    Not sure I can provide you with the concrete solution but I think it would be nice if you can tell us a bit more about your Umbraco solution.

    What version of Umbraco are you seeing this on? Have you done some custom stuff that does anything with the examine indexes or is it just vanilla Umbraco? No extension of backoffice functionality using the Umbraco API? What 3rd party packages are you using? Is it happening locally or only in production or both places?

    Hi Jan

    I use umbraco 7.2.2 and this bug was occured in my production three months ago (I built project above one year).

    Currently, I search on my website which throw an exception "System.IO.FileNotFoundException: no segments* file found in Lucene.Net.Store.SimpleFSDirectory" in log file. I don't use third party and just use basic umbraco. It also relates this post   

     https://our.umbraco.org/forum/developers/extending-umbraco/27569-Examine-not-indexing-at-all

    My solutions are:

    + Removing Examine Index folder in App_Data

    + Restarting IIS again and waiting for a few minutes.

    My Site was worked again but it can occur more. I don't see this exception at local, I think local is not enough to show this exception.

    Tam,

    When not go to developer section and rebuild the index from there?

    Regards

    Ismail

    Ismail Mayat,

    This can not do because developer section is not shown information of index, you can see my image as below.

    click on indexers, or is that not working? if not working then chrome f12 and see if you are getting any console errors.

    Regards

    @Ismail Mayat,

    I also debug on chrome F12 and my console just show information. 

    1. Message"An error has occurred."

    It is difficulty to debug it.
