Redbiom search issues in Qiita-rc

[tanaes]

Updating as I find them.

1. searching metadata for two words separated by a space causes search to freeze -- infinite spinning wheel.

2. searching for taxa doesn't seem to work.

3. Typos:

"Taxon: The search will be only on close reference" -> "Taxon: The search will be only on closed reference"

"Warning! No samples where found!" -> "Warning! no samples were found"
