Hey there,

I'm looking to add the ability to search specifically on the body. I
was poking around in the indexer, added these lines and reindexed a
few tags. It appears to work!

I was just wondering if there's anything I'm missing? That seemed a
bit too easy. I noticed there are some NOTMUCH_FIELDS that I'm not
sure what they do.

If anyone has any xapian knowledge that could shine some insight into
what the next steps might be, if any.

Thanks!
Will
