This seems to be a difference in how Zebra and ES operate

In Zebra a search like:
ti:cats dogs
will search for records with both 'cats' and 'dogs' in the title

In ES the same search is treated as
ti:cats _all:dogs
because spaces end an index

To perform the same search as Zebra, ES expects:
ti:(cats dogs)

For searching from the simple search bar this seems to be an issue of learning
syntax. When using the advanced search, however, I would expect that two terms
entered into a single box would both apply to the selected dropdown

To recreate:
1 - Find two records 
  - in the first add the words kangaroo and bucket to the title
  - in the second add kangaroo to title and bucket to publisher name
2 - in the search box try:
  - ti:kangaroo bucket - both titles returned
  - ti:bucket kangaroo - only first is returned
  - ti:(kangaroo bucket) - only first is returned
  - ti:(bucket kangaroo) - only first is returned
3 - From advanced search set an input dropdown to 'title'
  - bucket kangaroo - returns only the first
  - kangaroo bucket - returns both
  - (bucket kangaroo) - returns only the first
  - (kangaroo bucket) - returns only the first

The parens in 3 reflect the expected behaviour (i think) and should be added by
default
