Qlik Sense 3.1.x - Engine Search Index

Hello Everyone,

What benefit does this index feature provide? The description is fairly vague. I am a Sense system admin and one of my developers is asking for me to turn it off. But they don't even know what it does. I have looked through a number of online resources for Sense 3.1.x for this index feature and cannot get a clear picture of what it does. I do not want to turn off this indexing feature, unless it does something that I can discern as undesirable based on how my company uses sense.

"The QMC now has an engine setting: Create search index during reload, which improves the first search experience for a user."

"The first search experience". Which "first search"? At what point on the hub, does this come into play?

thank you.

Re: Qlik Sense 3.1.x - Engine Search Index

Hi Travis,

We were experiencing some issues with Qlik Sense while Creating Search Index process, when I found your question and an article about the Qlik Sense parameter: "CreateSearchIndexOnReload="; This article could help you clarify your doubts about this feature. Create Search Index On Reload

This article explains that the "Search Index" is a physical file on disk associated with each individual Qlik Sense application, it could be an issue if you have a multi-node site, because the "Search Index" file could be created (by Qlik) on the wrong node, then the Qlik Sense Application will create another one if it is running on a different node, in the end, you may end with several "Search Index files" all over your nodes.

Hope this helps,

Re: Qlik Sense 3.1.x - Engine Search Index

My two cents... With shared persistence all the apps are stored in single location and so is the physical file related to search index. I ran some tests and looks like when I do a search in app then only index are being created in Qlikshare\Apps\Search folder. If I do a reload it doesn’t create the corresponding app folder however at the same time if I set the variable (set CreateSearchIndexOnReload=1;) in load script it does create during the reload.
