Hi All,

Got a really strange issue where our examine indexes randomly (I say randomly because we haven't yet found the exact trigger) loose some fields.

For example if we take our site search index which looks like this:

• Documents in index - 336
• Fields in index 21
• Has deletions? false (0)
• Optimized? true

Sometimes our client is reporting that nothing is returned in the site search, when this happens I look at the search index and it looks as follows:

• Documents in index - 336
• Fields in index 19
• Has deletions? false (0)
• Optimized? true

If I simply click the "RebuildIndex" button in the Examine Management tab for the missbehaving index, once it finishes it's fine. It's back to 21 fields but I cannot for the life of me identify what would cause these fields to be removed.

Could anyone suggest what could cause this? What sort of code I could search for in the code base that is making this happen?

If I can identify the cause, I'm hoping I can fix it but I need your help with ideas for things to search for or ways to catch the cause!

Thanks,

Nik
