Forum How long does the REINDEX of the Search supposed to take? 2 days?
 

We are running Version 4.2.0 Patch Level 2

How long does the REINDEX of the Search supposed to take? 2 days?

In the AdminCP it reads the following:

"To rebuild the search index . . . This can be done via Maintenance > Update Counters. Reindex can take a long time for large boards."

Question 1: The last time I did this, it took 1-2 days. Is this normal for a board with 500,000 posts ??

Question 2: While the Reindexing is running during the day, are any other forum functions affected whereas the forum would not operate as usual?

Question 3: Is there a backup provision of the current Search Index (which is required to be deleted before rebuild can start) that can be restored at a later time should the reindex and rebuild fail?

Question 4: The Search Rebuild option box titled 'NUMBER OF ITEMS PER BATCH" has a default of 250. The last time I tried lowering it to 100 to see if the server would get all the way thru. But as the 100 per batch rolled along for an hour or two, it gradually started to roll along slower and slower and slower to where it eventually stopped. I am not sure why or what else I could have done.

Thank you,

David
