How to use fess to recreate index

(from github.com/ghost)
Hi I read some of the old post.
When I add some filters in my standard_analyzer at fess.json.

I saw some people said you need to “re-create fess index” or “re-index your fess” then can work
These two is the same meaning??
I don’t know how to “re-create fess index”

Or only mean these two processes at below?
1.Re-run Default Crawler.(I only see the sign from active to running)
2.If “Check Last Modified” is true, set it to false before starting crawler.

Please give me some exlaination thanks

When I add some filters in my standard_analyzer at fess.json.

fess.json is used at first startup time to create fess.yyyymmdd index.

“re-create fess index” or “re-index your fess”

They are different.

1.Re-run Default Crawler.(I only see the sign from active to running)
2.If “Check Last Modified” is true, set it to false before starting crawler.

The above is re-index.
If you want to update words on dictionaries, it’s re-index.

To re-create index,

  1. Delete fess.yyyymmdd index on dashboard
  2. Stop Fess
  3. Start Fess
  4. A new fess.yyyymmdd index is created automatically

If you want to change analyzer settings, re-create is needed.

Here is another question .
How do I check and set the crawler data store location to paticular index?
I want to check the store index because after I do the recreate and re-index, I check the data in my 9201 port at default crawler, I didnt see any data and when I do the search in search bar I didnt get any searchresult.
Should I do anything beside the re-index to get the result??

thx man
