Post Indexer is being Inconsistent

Hi

I am happily running Post Indexer and WPMU Google Maps Plugin

However, I seem to be having some issues.

I run the network=true statement to place markers on a map of posts network wide of a certain tag post.

With one tag name it works. With the other it does not.

The posts are extremely similiar on the same blog but it does not load to the blog where my map is.

I obviously have indexer and wpmudev google maps running network wide.

I can go off and create 4 posts and none of them show. I can then display posts that are 2 months old.

It is as if indexer has stopped logging posts on occasion.

Can we get a re-index button in indexer's backend?

Cheers

Johnny
