I've been attempting to search SO for answers (and *only* answers) containing the string `plz` using the [Advanced Super Ninja Search Options](http://stackoverflow.com/search). 

The query I used is: 

> [is:answer plz][1]

However, the results returned were not what I expected: 

![Screen grab of search][2]

Firstly, the results returned match **questions** where the string `plz` appears only in the title, and not in any of the answers. I've checked and none of the answers, comments, or anything else on those pages contain `plz` except the question title. 

Secondly, the hyperlinks of those matched questions link me to **answers** on those questions, but as I said, those answers don't contain the `plz` string I searched for. 

Examples of links returned by that search query: 

 - [`http://stackoverflow.com/questions/6637763/postgis-postgres-geocoding-help-plz/6637861#6637861`](http://stackoverflow.com/questions/6637763/postgis-postgres-geocoding-help-plz/6637861#6637861)
 - [`http://stackoverflow.com/questions/3981195/php-5-3-3-fails-to-validate-xml-against-nested-xsds-plz-help/5288415#5288415`](http://stackoverflow.com/questions/3981195/php-5-3-3-fails-to-validate-xml-against-nested-xsds-plz-help/5288415#5288415)

My questions: 

1. Is this [meta-tag:status-bydesign] or a [meta-tag:bug]?
2. If this *is* [meta-tag:status-bydesign] (and it seems strange to me if it is), is there any way to search just answer body text?
