Magento Index Management – Fix Catalog Search Index Broken

catalogsearchce-1.8.1.0reindex

I was trying some exetension, but after I installed "Ajax Search by LitExtension", my search index is broken.

Catalog Search Index says "Reindex Required". So I did.

Then I get this error. I cannot reindex it and also error message is somehow empty.

I deleted var/report as suggested here :

Catalog Search Index not changing status "required index"

but no luck.

How can I fix this?
I use magento 1.8.1.0 .

I solved this issue by changing Attribute to "Searchable" >> "No". In my case, to change tax_class_id did the trick.
